What is DevOps engineering **A DevOps Engineer typically focuses on: CI/CD (Continuous Integration / Continuous Deployment): Setting up pipelines that automatically build, test, and release code updates quickly and safely. Infrastructure as Code (IaC): Managing cloud infrastructure using code (e.g., Terraform, AWS CloudFormation). Monitoring & Logging: Ensuring systems are observable, with proper logs and metrics for troubleshooting. Collaboration: Bridging gaps between development, QA, security, and operations teams to foster a culture of shared responsibility. Why It Matters: Reduces errors and downtime. Enables teams to respond faster to changes or incidents. Promotes a more collaborative and agile workflow. DevOps Engineers are problem-solvers who work across technical and organizational boundaries. They must understand both code and infrastructure, and they play a vital role in enabling modern, scalable, and resilient systems** _KEY BENEFITS OF DevOps 🚀 1. Faster Software Delivery ✅ 2. Improved Software Quality 🤝 3. Better Collaboration 📉 4. Reduced Downtime and Failures 💸 5. Cost Efficiency ☁️ 6. Effective Cloud Utilization 🔄 7 Continuous Improvement**** 🔐 8.

Background: The Long Tail Effects of Cowardice Hi friends. It's James again. Today is my birthday and I feel I don't have a lot to show for it. Five years ago, in 2020 I posted on Dev.to about creating 100 React projects in 100 days (link here) to learn front end development and get a full time job in the industry. That mini-marathon of React projects got me some retweets from indie dev sites and the Dev.to community, and a little notoriety in the self-taught Javascript learner space. The projects repo (link) has 94 stars on it and 44 forks, which is cool, I also eventually did get a full time software engineering job at a startup, in part because someone in my network had seen the posts. It led to some really fruitful things and a whole career in the industry, plus eventually a web deve…  ( 7 min )

When it comes to coding with AI agents, most developers fall into one of two traps: Dump everything — a wall of requirements in a single prompt. Start coding cold — hoping the agent "just gets it." Both lead to what we call: spaghetti output. Here’s what actually works in practice when you're coding with AI. “Tell the agent what classes to care about, not just what problem to solve.” Instead of explaining the entire use case upfront, write high-level class or module definitions first. This acts as a skeleton and gives structure to the agent's reasoning. ✅ Good prompt: class QueryPlanner { plan(): Plan[] } Follow up with: "Now implement this based on user input…" Why it works: LLMs are great at filling gaps, but not great at building the frame. Vibe coding works best when you constrain the context window. "Give it less, guide it more." Instead of a big problem blob, chunk your work: Break large tasks into subproblems Prompt the agent on each chunk with a clear goal Use role-based prompting: "You are a planner… now you're an executor." Yes, even for AI. Giving agents tests first creates a performance boundary. It tells them what “done” looks like. // Goal: write a planner that outputs valid steps expect(plan).toContain('search Amazon') Agents that know the output constraints write cleaner, more relevant code. Avoid long prose. Use code blocks, short bullets, and examples. Use consistent naming: "agent", "task", "goal". Be specific in stages: e.g., “Now plan”, “Now execute”, “Now test”. Vibe coding isn’t just vibes. interface-first, scoped prompting, and test-driven generation. And when it clicks, it feels like pair programming with a genius assistant.

Why I Built ai-docs: Managing the Growing Chaos of AI Context Files When developing alongside AI agents, one of the first headaches that arises is how to manage the flood of context files they generate. Here are a few specific challenges I kept facing: As your AI coding assistant evolves, you naturally want to externalize and back up its memory files. These files are not deterministic and will inevitably differ across local environments and each developer's. Git merges often lead to nasty conflicts. During code review, these files just get in the way. Yet simply ignoring them with .gitignore is risky to disappear. You still want to back them up remotely. That’s when I realized: maybe these files don't belong in the main branch at all. And that's how ai-docs was born. GitHub - trknhr/ai-d…  ( 4 min )

Memory separates a basic script from a smart agent. But too much memory makes agents slow, confused, or even useless. At AgentNet, we design agents that remember just enough — and forget everything else on purpose. Think of agent memory like packing for a mission. Fast, disposable, now-only. Like remembering a phone number just long enough to dial it. Example: A to-do bot hears “Add eggs to the list,” and holds that info just long enough to write it down. After that? Gone. Cached between steps. Great for multi-hop interactions or workflow context. Example: A shopping agent remembers your cart across five pages, but clears it after checkout or inactivity. Stable, retrievable, structured. Indexed memory that lives in a database or vector store. Example: A sales agent recalls prior deals by customer name and recommends similar options. You didn’t re-teach it — it learned. Don’t hoard. Keep what’s meaningful. Discard noise. Scope your recall. Ask: "What should I remember... and when?" Index smartly. Use tags, timestamps, or role-based segmentation. An agent that remembers is an agent that grows. Originally published on AgentNet  ( 3 min )

“I didn’t modernize my stack. I rethought my system.” I was tasked with supporting and enhancing an eAdvice distribution system at my bank. The problem?

The first round of the UEFA Women's Euro 2025 is finished. Do teams win more with strong attack, or with strong defence? This is part of my personal data project. I’m learning sports analytics by doing real analysis with Python. All the data is from the first 8 matches of the tournament. Match data: www.flashscore.com Place data: www.uefa.com Weather data: http://timeanddate.com Tools: Python(Pandas, Numpy, Matplotlib) For each match, I looked at: Who won the match Their attacking stats: shots, shots on target, expected goals (xG), big chances Their defensive stats: tackles, clearances, interceptions This tournament is in neutral venues, so I didn’t look at "home vs away". winning team vs losing team. I made two bar charts: Attack stats of winners vs losers Defence stats of winners vs losers In 6 out of 8 games, the team with stronger attack (more xG, shots, chances) won. But something interesting happened on July 2nd. So defence can still win games, but not always. I also checked weather and match time. Could that make attacking harder, and help defensive teams? In general, strong attack wins in this tournament. But in tough conditions (like July 2nd), defence and efficiency can beat big attack numbers. This is why I enjoy football data — it tells the full story behind the score. This project is part of my journey to become a sports data content creator.

“Work harder on yourself than you do on your job.” — this idea alone could change your life forever. If you work hard at your job, that’s great — you’ll earn a living, pay your bills, maybe even upgrade your laptop once in a while. But if you work just as hard on yourself, your results can multiply. Because when you grow as a person — not just as a dev — your value grows too. Not just for the job market, but for life itself. You can have more than you have now, simply because you can become more than you are. Triple your value — triple your income. Multiply it by five — and you might just unlock financial freedom with your next pull request. But here’s the twist: success isn’t something you chase. attract by becoming valuable — by becoming the kind of person who draws opportunities in. Become responsible. Resilient. Skilled. Communicative. Curious. Strong. That’s the kind of upgrade no framework can give you — but it changes everything. Learn new programming languages (and human ones too) Read books — not just docs Sleep instead of shipping just one more task Practice communication like it’s a dev skill (because it is) Understand psychology — especially your own Drop habits that drain you Build side projects — not just on GitHub, but in real life You’re not code — but you can refactor yourself. And when you do, the world will respond with a whole new version.  ( 3 min )

Latency: A Deep Dive into Network Performance and Reliability Introduction I was on-call last quarter when a critical trading application began experiencing intermittent failures. Initial reports pointed to application code, but deeper investigation revealed consistently high latency spikes – averaging 200-300ms – between our New York data center and the AWS region hosting a key microservice. This wasn’t a simple network congestion issue; it was asymmetric routing caused by a BGP peering issue with a transit provider, manifesting as increased latency on return traffic. The incident cost the firm significant revenue and highlighted the critical importance of understanding and proactively managing latency in today’s complex, hybrid environments. Latency isn’t just about speed; i…  ( 7 min )

NeuroShellOS introduces the idea of an AI-integrated operating system where intelligence is built into the core design, not added as an external utility. Unlike conventional systems that treat AI as an app or extension, this concept explores how artificial intelligence can serve as an infrastructure layer, enabling natural language control, intelligent automation, and privacy-first design. Sample 1 presents a conceptual application of this vision. It focuses primarily on outlining the main features and base structure of the NeuroShellOS concept. The content highlights offline-capable AI integration, modular edition-based system layers, and user-centric customization models. This document is not a complete technical implementation or architectural breakdown. Rather, it introduces essential ideas that could guide future development. The release is made publicly available under the Creative Commons Attribution-ShareAlike 4.0 International license and is intended for conceptual reference, adaptation, or further exploration. Main repository (core concept): https://github.com/hejhdiss/NeuroShellOS View Sample 1 PDF: https://hejhdiss.github.io/NeuroShellOS-part-1/ This project remains open for collaboration, reinterpretation, and deeper development in any direction that builds upon its foundational principles.  ( 3 min )

Does nobody build stuff just for fun anymore? When did we stop tinkering just because something was interesting? When I started college back in 2019, I started tinkering with programming languages I fell in love with C, then C++, then BOOM I was introduced to Python by Tulesko, and like any sane person, I felt like god using len() for the first time to calculate length of an array. Then I learned JavaScript and TypeScript, another game changer and helped me secure my first internship and eventually job. I was over the moon, enjoying the journey, having fun, learning new things everyday. Promises, async await, event loop was learning a fair share of data structures on the side as well. And then something shifted, 6 Years have passed since I wrote my first line of code. I have explored multiple languages till now, Rust, Go, Haskell, Perl Never felt the joy again, It was gone. Because most of the time it was just for ticking checkboxes for job changes/ salary hikes. Never just to learn, just to tinker with something new for fun. When I see students today. They are missing out on this entirely. They are either too busy to complete the YC application or building their micro saas for financial freedom or building the next revolutionary AI wrapper. Man, just build for the fun of building, enjoy the process, before its too late. Until the next Rant, Pees out.  ( 3 min )

Introduction Welcome 👋 to this blog. In this blog, we will learn about the rsync command-line utility on Unix/Linux systems. A command-line utility is a program or tool that you run using the CLI(Command Line Interface) instead of the GUI(Graphical User Interface) rsync stands for remote sync. It is a fast and extraordinarily file-copying tool. It is capable of file transferring from a local host to any remote host. Rsync is most popular for its delta-transfer algorithm, which allows only to send data by sending only the differences between the source files and the existing files in the destination. Rsync finds files that need to be transferred using a lqquick checkrq algorithm. I have two folder directories with the name local and remote. I am treating local as the file system in my lo…  ( 5 min )

Hello and welcome to the new blog When I think of these websites, a few topics come and a few alternatives, mainly of the aggregator platforms or content platforms.

(Първо публикувано на 08.01.2017) Днес ще разгледам един прост комбинаторен алгоритъм за “кодиране” на пермутации. Какво представляват пермутациите? Общо взето, те са комбинации, при които редът на елементите има значение. Харесва ми обяснението предоставено от MathIsFun — ако кажем “плодовата ми салата съдържа ябълки, грозде и банани”, редът на елементите няма значение (можем лесно да кажем, че салатата съдържа “банани, ябълки и грозде” и твърдението пак ще е валидно) и тогава говорим за комбинация. Но ако редът има значение, например когато кажем “PIN кодът на телефона ми е 1337”, тогава говорим за пермутация, тъй като не би било правилно да кажем, че кодът е 1373 или някакво друго число. Тук ще говорим за пермутации без повторения на елементите, така че ако става дума за пермутации от 3…  ( 5 min )

Week 2 of Hustle2Grand is done, and it was intense. On Tuesday I launched LogicLore, my edtech platform that teaches computer science to kids through themed challenges. The product feels solid, but I didn’t market it enough — no users signed up. Definitely something I’ll need to improve soon. Then in just two days, I built and launched VibeFight, a launch arena for “vibecoded” projects. It got 140 visitors in the first 2 days, but only 3 submissions. I shared it on Reddit and got tons of feedback, which I summarised in a post here: Everyone said it was genius. No one used it. Medea ・ Jul 4 #webdev #vibecoding #javascript #learning Biggest takeaways: People lurk more than they interact Comments ≠ users Users need a reason to come back or take action (incentives, community, visibility, etc.) On top of that, I prelaunched VibePatch, a security audit agency for vibecoders. It offers manual website reviews before launch to catch common vulnerabilities. I priced it at £50 to start with, but no customers yet. Shipping fast is great, but without proper marketing or distribution, nobody shows up It’s easy to confuse interest with traction — validation needs action, not compliments Burnout is real. After pushing three projects in two weeks, I hit a wall I’m taking next week a bit slower. My plan: Revamp my portfolio and clean up all the projects List GameGift for sale — it's a strong idea, but someone else might market it better than I can No new launches — just maintenance, polish, and regrouping After that: I’ll fix VibeFight using the feedback I collected Try more targeted marketing for LogicLore, which I still believe can be a core income stream Push for my first customers with VibePatch and start exploring more of the cybersecurity space Still a long way to go before I hit £1,000, but each week I'm learning what actually works — and what doesn’t.

1. Introduction: Code Is Just the Starting Point When most people think about web development, they picture lines of code HTML, CSS, JavaScript, maybe a fancy framework or two. And sure, writing clean, efficient code matters. But that’s not the full picture anymore. The best developers today understand that their job goes far beyond syntax. It's not just about getting the code to run it’s about making sure that what you're building actually solves a real problem for real users. Whether it’s making a checkout process faster, improving performance on slow mobile networks, or just making a site easier to navigate for someone using a screen reader that’s the real challenge. Web development has evolved. We’re no longer just “website builders.” We’re problem solvers, user advocates, and system…  ( 7 min )

Introduction In the realm of DevOps, where speed and reliability are paramount, deployment strategies play a crucial role in ensuring seamless releases. One such strategy that has gained significant traction is Blue/Green Deployment. Blue/Green Deployment involves maintaining two identical production environments, one 'blue' and one 'green.' At any given time, only one environment serves live traffic while the other remains idle. This setup allows for smooth transitions during deployments without impacting end-users. By switching traffic between the blue and green environments, organizations can achieve zero downtime deployments. This ensures that users experience uninterrupted service during updates. In the event of issues post-deployment, rolling back changes is simplified in a Blue/Green setup. By directing traffic back to the stable environment, teams can quickly mitigate any issues. Utilize tools like Terraform or CloudFormation to define and provision infrastructure. This ensures consistency between the blue and green environments. resource "aws_instance" "example" { ami = "ami-0c55b159cbfafe1f0" instance_type = "t2.micro" } Implement automated testing to validate deployments in both environments. Tools like Selenium for UI testing and Jest for unit testing can streamline this process. describe('Calculator', () => { test('adds 1 + 2 to equal 3', () => { expect(sum(1, 2)).toBe(3); }); }); Blue/Green Deployment offers a strategic approach to deployment in DevOps, enabling organizations to release software with confidence and agility. By leveraging this methodology, teams can mitigate risks, ensure high availability, and deliver exceptional user experiences.  ( 3 min )

A Duet of Performance and Safety: Technical Analysis of Modern Web Frameworks As a third-year computer science student immersed in the world of computer science, my days are consumed by the logic of code and the allure of algorithms. However, while the ocean of theory is vast, it's the crashing waves of practice that truly test the truth.

Building a rootless framework is difficult, but still Proton was built with a very intentional design choice: its components are allowed to return anything - from DOM Nodes, to primitives, and null/undefined. This flexibility is not a bug, but a feature. However, this freedom comes with sharp edges: when null is returned, no anchor is created, and the view replacement logic has nothing to latch onto. One of core goals of Proton is to eliminate the concept of "Root Components" entirely and embrace fully "Atomic Components" - meaning self-contained, relocatable, and behaviorally independent. For example: function Component() { setTimeout(() => this.view.set( Another layout ), 1_000) return Some layout ) const com…  ( 4 min )

This is a submission for Frontend Challenge: Office Edition sponsored by Axero, CSS Art: Office Culture. For this CSS Art piece, I wanted to capture the essence of contemporary office culture where technology and personal elements blend to create a productive yet human workspace. My inspiration came from: The Digital Transformation - How modern offices revolve around technology with computers as the central hub of productivity *Developer Culture *- The ubiquitous coffee, mechanical keyboards, and coding environment Work-Life Balance - Personal touches like desk plants that bring nature into digital spaces Continuous Learning - The books representing ongoing skill development in tech Collaboration - Floating icons symbolizing communication, ideas, and teamwork I aimed to create a scene that resonates with today's hybrid work environment while celebrating the tools and rituals that define our office experiences. Live Demolink! Creating this CSS artwork was a journey of pure creative expression through code. I'd love to expand this project by: Adding interactive elements (e.g., turning on/off the monitor) Creating day/night cycle animations Developing additional office scenes (meeting rooms, break areas) Implementing a 3D perspective with CSS transforms Adding sound effects for a more immersive experience This project reminded me that CSS is not just a styling tool but a powerful medium for artistic expression. The modern office is more than just a physical space—it's an ecosystem of tools, rituals, and human connections that I've enjoyed representing through code.  ( 3 min )

Hi, I’m Shaheen Amjad, a full-stack web developer. I have more experience with back-end APIs, having two years of experience in both back-end and front-end, but I like APIs more. What do I need? The experience I’ve gained over the past two years has been in the projects I’ve created, which are huge. I’ve also created a project similar to Shopify ( it was my first project btw ). I’ve created many projects, but why? Because no one has interviewed me. I’ve also tried freelancing, but no one has contacted me! I’m 16 years old, and I only have internet access and a laptop (4GB RAM, Intel Core i3 processor). I don’t have any money, and I want to profit from the things I love, just like the guys I found on YouTube when they publish their SaaS projects. What I need from you all is for you to give me your requests, your ideas, everything. I’m really exhausted from looking for opportunities and ideas. I’ve built three APIs, and they haven’t worked. I’ve marketed them on social media, but no one has shown interest. So, I’m responsible for the requests, because I don’t know what needs to be solved. So, I said I can come here and ask people for requests or needs to create projects. Whatever your specialty… please give me some ideas. If you’re a developer, please provide me with any ideas you can think of. If you have an idea, you don’t need a database. That would be even better because I don’t have any money to buy one. thanks for everyone -shaheen amjed  ( 3 min )

1. What is Virtualization? Virtualization is the process of creating a virtual (rather than physical) version of something, such as a server, a desktop, a storage device, an operating system, or network resources. It allows multiple virtual systems to run on a single physical system, maximizing hardware efficiency and flexibility. Key Concepts: Virtual Machines (VMs): Software-based emulations of physical computers. Each VM runs its own OS and applications. Hypervisor: Software that enables virtualization by managing and allocating resources to VMs. There are two types: Type 1 (bare-metal): Runs directly on hardware (e.g., Microsoft Hyper-V, VMware ESXi). Type 2 (hosted): Runs on a host OS (e.g., VMware Workstation, VirtualBox). Resource Sharing: Virtualization allows CPU, memory, a…  ( 4 min )

In the construction industry, timing and budgeting are everything. But there's one surprisingly frustrating issue that affects millions of builders, contractors, and homeowners across countries like India and Pakistan — there’s no simple way to check updated cement prices online. Yes, you read that right. If you’ve ever tried to build a home or manage a construction project, you’ve probably noticed how cement prices vary wildly from region to region, and even between local dealers in the same city. You’ll find prices on WhatsApp, through word of mouth, or by calling up suppliers one by one — but rarely in a structured, updated, and trustworthy format. This gave me an idea: “What if I built a tool that simply tracked cement prices in one place — fast, clean, and easy to use?” As someone wit…  ( 6 min )

📝 This is cross-posted from my personal site - https://chrisdavies.dev . A common adage for any developer choosing a database technology is "just use Postgres". While this advice remains well-intentioned, it deserves a fresh look in 2025. Thanks to a wave of recent innovations and acquisitions, PostgreSQL providers now resemble JavaScript frameworks of the 2010s - there’s seemingly a new one to consider every six months. Just choosing PostgreSQL isn’t enough anymore - there is an entirely new decision tree to follow before you can launch a system. 🌳 TL;DR: The answer to "Which one do I choose?" is always "It depends", but this post signposts exactly what those deciding factors are. ⚖️ Postgres uses an elephant as its mascot.

🚧 Scope Will Creep - Your Job Is to Tame It, Not Eliminate It No matter how well you plan, scope creep is inevitable. Saying “No” can damage trust. Saying “Yes” to everything can break the timeline. 🔧 Instead of pushing back, say: “That’s a great feature; let’s log it under Phase 2 so we can stay on track for the current delivery.” This one sentence helps: 🔑 Best Practices to Stay in Control 📋 Start with a clear Scope Statement - Define what’s included, what’s excluded, and what success looks like. Use a simple Work Breakdown Structure (WBS). 👥 Involve stakeholders early & often - Don’t assume. Confirm. Regular check-ins help align expectations before they turn into surprises. 🧾 Use a formal Change Request process - Every new idea should pass through effort, time, and cost filters. Approve wisely. 🗂️ Maintain a “Parking Lot” or Phase 2 Backlog - A space for great-but-not-now ideas. It shows you’re listening — while protecting current goals. 📊 Track progress against the scope baseline - Weekly updates reveal scope drift early. Compare planned vs. actual often. 🚨 Educate gently on scope creep risks - Sometimes people don’t realize the impact. A simple heads-up like “this might delay things” makes a big difference. ⏱️ Timebox when possible - Short sprints and fixed milestones help keep momentum and clarity. 💡 Final Thought Scope creep doesn’t mean chaos. The key is to channel that energy without losing direction. You’re not here to block ideas - but to guide them. Be the compass 🧭 - keep the course clear, focused, and flexible.  ( 3 min )

AI Menu Visualizer: Bringing Restaurant Menus to Life This post is my submission for DEV Education Track: Build Apps with Google AI Studio. I created an AI Menu Visualizer that transforms static restaurant menus into vibrant visual experiences. Using Google's Gemini AI, the app can analyze both English and Chinese menu text, identify dish names, and generate photorealistic images for each dish. The key prompts include menu text extraction with structured JSON output and carefully crafted image generation prompts for appetizing, professional food photography. Code is here: [https://github.com/williamhatch/ai-menu-visualizer] Key Features: Bilingual menu support (English & Chinese) Real-time dish detection and image generation Modern, responsive UI with Tailwind CSS Progress tracking for multi-dish menus Error handling and graceful fallbacks Building with Google AI Studio and Gemini was surprisingly intuitive. Key takeaways: Multimodal Power: Gemini's ability to understand both text and images made menu analysis seamless. The model handles bilingual content exceptionally well. Structured Output: Using the responseMimeType: "application/json" config ensures clean, parseable responses - crucial for production applications. Image Generation Quality: Gemini's Imagen model produces consistently high-quality food photography, though prompting requires careful crafting for best results. Developer Experience: The @google/genai SDK is well-documented and TypeScript-friendly, making integration straightforward. The most challenging aspect was optimizing the image generation prompts to produce consistent, appetizing results across diverse cuisine types. The solution was to standardize the prompt structure with specific photography-focused language. This project demonstrates how AI can enhance real-world dining experiences by bridging the gap between text menus and visual presentation.  ( 3 min )

Not sure if this will resonate with others, but something weirdly powerful happened to me recently. I was feeling stuck — not in terms of code, but direction. I’d fix a bug, build a small feature, help someone, learn something — and then forget it the next week. It all felt like I wasn’t making progress, even though I was. Then I started logging. Like, really small entries: "🔥 fixed weird async bug after 2 hrs—learned about event loop.” “I don’t write code — I plant bugs and call it ‘feature growth’ 🙃.” “🚧 messed up prod config — learned to double check .envs lol” Nothing fancy. Just me and my thoughts. Sometimes code-related, sometimes personal growth. I used a platform called Devmate — it gives a kind of "command-line journal" for devs. It felt like a private logbook — but if I wanted, I could also share it with others. And it slowly started showing stats, clone count, logs per day, and even latency time (I’m a sucker for metrics 😅). What changed? I saw my growth clearly. I felt more accountable, even on bad days. I now have a timeline of my effort, not just achievements. Looking back, I realized how far I’ve actually come. And weirdly... I stopped comparing myself to others. I’m not trying to "sell" anything. I just wanted to share this with other devs who might be feeling like they’re not doing enough—when in reality, they’re doing a LOT. They just aren’t capturing it. Anyway, if you feel like giving it a try: ➡️ https://devmate.space (it’s free and lightweight and honestly feels kind of calming.) Curious—does anyone else keep a dev journal or log?

What each of HTML, CSS, and JavaScript does How to set up your files How to write a basic page layout How to add styles and interactivity How to run it in your browser Before writing code, it helps to understand what these three languages do: HTML (HyperText Markup Language): Creates the structure of the web page. CSS (Cascading Style Sheets): Adds style, color, and layout. JavaScript: Makes things interactive (like buttons, sliders, forms). �…  ( 4 min )

By [Your Name or Brand] When you’re just starting out — whether as a freelancer, consultant, or small business owner — one of the trickiest decisions you’ll make is this: How should I price my work? You’re not alone. Many beginners get stuck in this decision loop, trying to strike the perfect balance between getting clients, being fairly compensated, and not scaring people away with high fees. Let’s break down the three most common pricing strategies — hourly, fixed, and value-based pricing — and look at how you can confidently position yourself at any price point, even as a beginner. Hourly Pricing: The Beginner’s Comfort Zone What it is: Charging based on the number of hours you work. 💡 Example: \$50/hour for design services. Why it’s beginner-friendly: Easy to calculate.

Claude Code meets Nix: Your AI Assistant, Properly Packaged Ever had that moment where you switch Node versions and suddenly half your global tools vanish? Yeah, me too. That's exactly why I packaged Claude Code with Nix. Here's the thing: Claude Code is fantastic. But when you're juggling multiple projects with different Node versions through devenv, asdf, or nvm, that globally installed npm install -g @anthropic-ai/claude-code becomes a house of cards. Switch to Node 18 for one project? Claude disappears. Jump to Node 22 for another? Good luck finding where npm stashed it this time. Most developers treat global npm packages like system utilities.

Imagine teaching a group of smart robots to play a team game — but first, they need to remember the rules and their roles. That’s what AutoGen does with State and Memory Imagine you have a bunch of talking robots (these are called agents in AutoGen). Each robot has a job to do—like answering questions, solving puzzles, or writing stories. But how do these robots remember what’s going on in the game? That’s where state and memory come in! Memory is like a robot’s notebook. So next time you ask it something, it can look back at the notebook and remember what you were talking about. 💡 Memory helps robots not forget! State is like the robot’s current mood or job. The state tells the robot: What it should do next What its goal is What’s already done 💡 State helps robots stay focused and not get confused! Let’s say you have: Robot A: Good at explaining things Robot B: Good at writing code Robot C: Asks the questions (that’s you!) All three robots talk to each other, and they share the same notebook (memory). work like a team! AutoGen is like the game master: It gives each robot a job (state) It gives them a shared notebook (memory) It helps them talk, think, and solve things together Why Should We Care? Without memory and state: Robots forget everything—like a goldfish! They repeat the same things They don’t work well as a team With memory and state: Robots remember what you said before They stay focused They finish tasks smarter and faster I love breaking down complex topics into simple, easy-to-understand explanations so everyone can follow along.

The AI integration possibilities are moving towards a fundamental shift. While APIs have served as the backbone of software integration for decades, a new protocol is emerging that promises to transform how AI systems interact with external tools and data sources. Enter the Model Context Protocol (MCP)—Anthropic's open-source standard that's redefining the boundaries between AI models and the applications they serve. For years, developers have relied on APIs to connect disparate systems. The RESTful revolution democratized software integration, enabling everything from mobile apps to enterprise systems to communicate seamlessly. However, when it comes to AI language models, traditional APIs reveal critical limitations. Consider a typical scenario: A developer wants to give an AI assistant …  ( 8 min )

Distance-aware queries are a core feature for modern apps—whether you're matching riders and drivers, showing events around a user, or surfacing the nearest warehouses for same-day delivery. The fastest, most accurate way to deliver those results is to compute great-circle distance inside your SQL engine with the Haversine formula, then let Eloquent give you a fluent, testable API. Mathematically sound. Haversine treats Earth as a sphere, producing realistic distances at planetary scale without the overhead of full ellipsoidal calculations. Pushes work to the DB. The heavy trig runs where your data already lives, slicing result sets before PHP ever sees them. Vendor-agnostic. Works in MySQL, MariaDB, Postgres, SQL Server—anything that supports basic trig functions. The Haversine formula gi…  ( 5 min )

Handling multi‑gigabyte uploads in a stateless app is painful: TCP throughput caps slow single‑request uploads, server disks fill, and Lambda containers vanish between requests. Modern teams therefore push the heavy bits straight from the browser to Amazon S3. S3M—a lean wrapper around S3's multipart and presigned‑URL APIs—removes the boilerplate. S3M works with any JavaScript front‑end, but in this post I'll give you some examples using Vue so you can see the flow end‑to‑end without locking you into a specific framework. Amazon limits a single PUT to 5 GB. Multipart uploads slice the object, let slices fly in parallel, and re‑assemble the completed object inside S3. Presigned URLs add a time‑boxed signature, allowing the browser to upload directly to S3 while your API remains stateless an…  ( 5 min )

Hey problem solvers! 🧠 Today we’re tackling an interesting design-based problem — where you don’t just compute once, but need to efficiently add values and count pair sums across two arrays. This one blends hash maps with careful indexing to keep operations optimal. Let’s break down how to structure the FindSumPairs class for the win! 🔧 You are given two arrays nums1 and nums2. You must: Implement a class FindSumPairs that supports two operations: add(index, val): Add val to nums2[index]. count(tot): Count how many pairs (i, j) exist such that nums1[i] + nums2[j] == tot. The class should efficiently handle many such operations. We fix nums1 as a reference array. We store a frequency map for nums2 so that count(tot) can be done in O(n) instead of O(n²). When add(index, val) is called, we …  ( 5 min )

AI is everywhere. But where it runs — and where your data flows — matters more than most teams realize. There are three main ways to deploy AI: On-premises AI (self-hosted, full control) Cloud-based AI (platforms like AWS, Azure, GCP) AI via third-party tools (like Notion AI, Canva AI, Make, etc.) Each option has trade-offs in security, cost, scalability, and control. The right choice depends on your infrastructure — and how much ownership you want over the stack. What it is: Running AI models locally on your own servers — either physical or private cloud.

Data Isn’t Just Power — It’s Liability Too Why Your Dataflow Matters More Than Ever in the Age of AI In 2025, “data is the new oil” is no longer just a cliché — it’s the currency of your business logic, automation, decision-making, and competitive edge. But while the buzz around AI and cloud tooling keeps rising, one critical component remains dangerously overlooked: your internal dataflow. Who has access? Where is it stored? When is it enriched, synced, analyzed — and by whom? And most importantly: When is it safe to run AI on it? And where? A dataflow is more than a series of spreadsheets and dashboards.

Introduction Both C23 and C++23 added the unreachable() and std::unreachable() functions, respectively, that insert undefined behavior into your program. (If you don’t know what undefined behavior is, you should definitely read that article first.) Ordinarily, undefined behavior should be avoided at all costs. So why does unreachable() exist and when would you ever want to use it? Its name gives a hint: it tells both compilers and programmers that the line of code on which unreachable is “called” is never actually called. What use is that? It allows you to: Suppress warnings. Perform a bit of optimization. It can do those things because the compiler is allowed to assume that undefined behavior never happens. It’s probably easiest to explain how unreachable() can be used to suppress …  ( 5 min )

Keep reading for the deeper why, plus a type‑safe pattern you can copy‑paste. createContext(defaultValue) returns a Context object with two keys: Context.displayName (plus legacy .Consumer) Consumers call useContext(Context) to read the nearest Provider’s value. …  ( 5 min )

After the Hackathon: FuturePath and the Road Ahead This is a submission for the World's Largest Hackathon Writing Challenge: After the Hackathon. When I first joined the World’s Largest Hackathon, I wasn’t sure what would come of it. I knew I wanted to build something that mattered — but I didn’t expect to walk away with a project that could become a real startup. What started as a sprint turned into a mission. During the hackathon, I built FuturePath — a career mentorship and planning platform for teenagers, powered by AI. The idea was simple: most students don't know what they want to do after high school, and the systems meant to guide them are either outdated, overworked, or not built with teens in mind. FuturePath helps solve this by offering: Personalized AI mentorship Dynamic care…  ( 4 min )

In certain scenarios, we need to initialize some resources, such as singleton objects, configurations, etc. There are multiple ways to implement resource initialization, such as defining package-level variables, initializing them in the init function, or in the main function. All three approaches can ensure concurrency safety and complete resource initialization when the program starts. However, sometimes we prefer to use lazy initialization, where resources are only initialized when they are truly needed. This requires concurrency safety, and in such cases, Go's sync.Once provides an elegant and thread-safe solution. This article introduces sync.Once. sync.Once is a synchronization primitive in Go that ensures a specific operation or function is executed only once in a concurrent environm…  ( 7 min )

Looking back, I’ve seen many merchants and partners go through the journey from Magento 1 to Magento 2 (Adobe Commerce), including myself. Now, we’re entering the next evolution, Adobe Commerce as a Cloud Service (ACCS). Each wave of change brought something new, but also taught us something valuable. And while it’s tempting to compare these transitions as just “technical upgrades,” the reality is that each one reshapes how we think and build ecommerce solutions. When Magento 2 launched, it came with real improvements, better performance, modern APIs, stronger security, a new SLA for support, and security compliance from Adobe. However, it wasn’t an overnight switch, mainly because we could leverage the upgrade opportunity to revisit some implementation points and reduce costs, while also …  ( 5 min )

Understanding "learn resume" for Beginners Have you ever started learning a new programming language and felt overwhelmed by all the concepts? Or maybe you've built a small project and aren't sure how to show it off to potential employers? That's where the idea of a "learn resume" comes in! It's a way to track your progress, demonstrate your skills, and build confidence as you learn to code. This is super important, especially when you're starting out and don't have a lot of professional experience. Interviewers love to see what you've been actively learning and building.

What Is Meta-Learning? Meta-learning — often called “learning to learn” — is the idea that an AI model can learn not just from data, but from the process of learning across multiple tasks. Think of it like this: Traditional ML: "Here's a task — learn it well." Meta-learning: "Here’s a bunch of tasks — figure out how to learn any new one quickly." It’s especially useful in situations where data is scarce or new tasks keep popping up (like personalized recommendations, robotics, or medical diagnosis). Few-shot learning is one of meta-learning's most powerful applications. It means your model can generalize to new classes with only a few labeled examples — sometimes just one or two per class. Meta-learning makes that possible by training models to adapt fast, rather than memorizing everyth…  ( 5 min )

A week ago, an interviewer asked me: Why do we need to manage state in a frontend application? Why can’t HTTP handle it for us? There can be multiple answers to this, but the simplest one is: HTTP is a stateless protocol. Each HTTP request is independent. The server doesn’t know anything about previous requests. Why So? Can’t We Make HTTP Stateful? Why Exactly? 1. Scalability When your application grows, you no longer rely on just one server. But because it’s stateless, any server can handle any request. 2. Simplicity This means: No need to track sessions or store user-specific context. GET /user-profile The server does: Validates token Fetches user info Responds No memory of this is retained after the response 3. Performance Stateful systems usually need to keep track of: User sessions…  ( 4 min )

About three months ago, I started my journey with Ansible, a configuration and Infrastructure as Code (IaC) tool used by over 20,000 companies. There were some genuinely great things about Ansible that made it enjoyable to work with: Push-based: I write the config, and it just goes over SSH. No need for a big control plane or cloud API. Agentless: No weird daemons to install on every server. Just SSH and vibes. Collections: A whole ecosystem of plugins for AWS, Docker, Kubernetes — you name it. But the problems started early. Ansible had me debugging ansible.cfg before I even wrote my first playbook. Along came the YAML mess and its indentation problems. Oh, and the autocomplete feature on VS Code? That’s just decoration.

If AI can write your blog post, your LinkedIn update, and even your product documentation… why bother learning to write at all? It’s a fair question, and one I asked myself before writing this blog. We’re living in a time when AI can spit out full articles, emails, and yes, even this sentence, faster than you can open Google Docs. It’s fast, it’s polished, and it even throws in a few buzzwords for good measure. So it’s easy to think: Why not let AI do the writing while I go make a sandwich? Here’s the thing: Just because you can generate 100 lines of text doesn’t mean anyone’s going to read them. Because writing isn’t just about stacking words together.

Trap Handlers in JavaScript Proxies: An In-Depth Exploration JavaScript, as a dynamic and versatile language, has evolved to embrace advanced programming paradigms, one of which is the usage of Proxies. Introduced in ECMAScript 2015 (ES6), Proxies allow developers to create objects that can intercept and define fundamental operations for other objects. The heart of the Proxy mechanism lies in "trap handlers," which are functions that provide custom behaviors for operations like property access, mutation, and reflection. This article delves deeply into trap handlers in JavaScript Proxies, encompassing their history, technical context, practical use cases, performance considerations, and more. JavaScript’s ability to extend its capabilities through proxies stemmed from the need for enhance…  ( 6 min )

🔁 MongoDB Transactions in Node.js — The Complete Guide with Mongoose If you think MongoDB isn’t meant for complex, multi-step operations like SQL transactions — think again. With replica sets and sharded clusters, MongoDB supports ACID-compliant transactions. And in this blog, I’ll walk you through how to use them in a real-world Node.js backend. Let’s say: You’re deducting money from one user and adding it to another. You’re updating multiple collections together (like orders + inventory). Or, you just want to make sure either everything is updated or nothing is. MongoDB’s default operations are atomic only at the document level. If you need multi-document atomicity, transactions are your tool. I'll be using Mongoose here. First, install it: npm install mongoose Connect to your databa…  ( 4 min )

This is a submission for the Runner H "AI Agent Prompting" Challenge I created a Chrome extension called SideSave, designed especially for content professionals, SEOs, and competitive analysis. The idea came from my own workflow writing search-optimized content, where I often need to analyze how competitors position themselves in Google's sponsored results. The problem is that these ads — although rich in copywriting, links, persuasive hooks, and keywords — disappear quickly. Just by refreshing the search or waiting a few minutes, the same ad may no longer appear. This makes analysis and later study difficult. SideSave solves this by saving ads with title, link, snippet, and a clear visual marker that it's a sponsored result. How I Used Runner H I used Runner H as a tool to…  ( 4 min )

AWS Certificate Manager (ACM) simplifies SSL/TLS certificate management for securing web applications. When using Amazon Route 53 as your DNS provider, generating a certificate is seamless. However, if you use a third-party DNS provider (e.g., GoDaddy, Namecheap, or Cloudflare), you may encounter a common error during certificate validation: Error: "One or more domain names have failed validation due to a Certificate Authority Authorization (CAA) error." This error occurs because ACM requires specific DNS records to verify domain ownership, and third-party DNS providers need manual configuration to allow Amazon’s Certificate Authority (CA) to issue the certificate. In this guide, we’ll walk you through troubleshooting and resolving this issue step-by-step. Access to your third-party DNS provider’s management console. Step 1: Understand the CAA Error Step 2: Add CAA Records in Your DNS Provider Save the changes. (Note: DNS propagation may take a few minutes to hours, depending on your provider.) Step 3: Request a New Certificate in AWS ACM Select Request a public certificate and click Next. Enter your Fully Qualified Domain Name (FQDN) (e.g., amalcloud.com or www.amalcloud.com). Optionally, click Add another name to this certificate to include alternative names (e.g., *.amalcloud.com for wildcard certificates). Return to your DNS provider’s DNS management console. Step 5: Wait for Validation dig CAA example.com Ensure amazonaws.com and amazon.com appear in the results. Incorrect CAA record syntax (e.g., missing 0 issue or quotes). By adding the required CAA and CNAME records to your third-party DNS provider, you can resolve the AWS ACM CAA error and successfully issue a certificate. This process ensures your domain is validated and your certificate is ready for use with AWS services. If you encounter persistent issues, double-check your DNS records, consult your DNS provider’s documentation, or contact AWS Support.  ( 5 min )

Intro Nowadays complex web apps that feature rich, dynamic UIs are taken for granted. And it's not surprising — the internet has come a long way since its inception. Initially, the internet wasn't built to support such dynamic and complex web apps. It was conceived to be a collection of HTML pages, linking to one another to form the concept of "web" that contains information. Everything was largely built around the so-called request/response paradigm of HTTP. A client loads up a page and then nothing happens until the user clicks and navigates to the next page. Around 2005, AJAX was introduced and a lot of people started to explore the possibilities of making connections between a client and а server bidirectional. Still, all HTTP communication was steered by the client, which required u…  ( 13 min )

Who your friends are says a lot about you. And in our ever-more digital world, public knowledge of who they are may be a major security risk to you. This risk has been spotlighted once again with the recent scandal of US national security adviser Michael Waltz’s exposed Venmo Friends List. Venmo, a popular American mobile payment app owned by PayPal, allows the user to sync contacts from their phones directly into the app as “friends”. These friends then populate the user's "Friends List" within the app, letting the user easily transact with their existing contacts without asking for their Venmo accounts. While it may seem common and user-friendly for apps to import contacts from your phone, the social media aspect of Venmo makes this feature dangerous because your Friends List, i.e. all y…  ( 6 min )

mock interview is a simulated job interview designed to mirror real interview scenarios. It provides candidates with a platform to practice their responses, refine their communication skills, and receive constructive feedback in a risk-free environment. This preparatory exercise is instrumental in building confidence and enhancing performance in actual interviews The primary purpose of a mock interview is to prepare candidates for real-life interview situations. It allows individuals to: Gain familiarity with common interview questions and formats. Receive immediate feedback on their responses and demeanor. Identify areas of improvement in both verbal and non-verbal communication. Develop effective strategies for articulating thoughts and experiences. By simulating the interview environment, candidates can reduce anxiety, improve their presentation skills, and approach actual interviews with greater confidence Regular practice through mock interviews helps in alleviating nervousness and building self-assurance. Candidates become more comfortable articulating their thoughts, leading to a more confident demeanor during actual interviews.

Participants can work on aspects like tone, clarity, body language, and eye contact, ensuring a more polished presentation.  ( 3 min )

Introduction Every day of developer's career, interaction with a programming language is the way to compile and run applications. If no errors found, it just executes and performs its job. Sometimes, new to intermediate developers have asked themselves at least one of the following questions: What happens when code is compiled? is CPU able to understand C# code? How variables, objects are handled in memory? What does "Run" mean? Questions before are completely valid. To answer them, .NET has a powerful platform doing so much work behind the scenes: The CLR. .NET CLR (Common Language Runtime) is the engine of the .NET environment where C# code is compiled and executed.

🧠 Context Today, I stepped back from building features to refactor and clarify the data relationships between the major entities in our system — Workspaces, Cases, Documents, Users, Tags, and Calendar Events. 📦 What I Did Simplified Relationships At first, we had awkward relationships like: Case having both workspaceId and a nested workspace reference, Document storing redundant workspace references already tied through Case. I cleaned this up using Prisma relations. Now, each document belongs to a case, and the case belongs to a workspace. This means fewer joins, less chance of inconsistency, and clearer logic in queries. prisma model Workspace { id String @id @default(uuid()) name String cases Case[] } model Case { id String @id @default(uuid()) title String workspace Workspace @relation(fields: [workspaceId], references: [id]) workspaceId String documents Document[] } model Document { id String @id @default(uuid()) title String case Case @relation(fields: [caseId], references: [id]) caseId String } Improved Naming Conventions Added Indexes for Performance prisma @@index([workspaceId]) @@index([caseId]) ⚠️ Lessons Learned You don’t need to get your schema perfect on Day 1. Design clarity = easier maintenance and faster development. Refactoring schemas early saves hours later. A simple, normalized structure beats clever tricks. 🔍 Bonus Debug Tip npx prisma migrate reset Just remember to back up your seed data first! ❓Question Let me know your approach!

Table of Contents Introduction Why chunking Why contextual chunking Why fixed-size chunking is insufficient How to implement contextual chunking Docling Google Gemini 2.5 Pro/Flash Conclusion In many enterprise settings, we often have documents which are highly structured and nicely formatted. There is often a hierarchical approach in how the information is structured. For example, there is usually a content page, and relevant information are often grouped by sections. The section numbers are also in running order, and often follow a certain convention, e.g. "d.d.d Header". When creating RAG for thousands of such documents, chunking is often necessary so that when queried, the chunks are of manageable length to be passed to LLMs as context.

A reflection on benfits of full text OCRization and how it becomes handly with LLM enables applications. Full Optical Character Recognition (OCR) of a document like a PDF offers a wide range of benefits, transforming static, image-based files into dynamic, searchable, and editable content. Here are the key advantages: Searchability: This is arguably the most significant benefit. Without OCR, a scanned PDF is essentially just an image, and you can’t search for specific words or phrases within it. Full OCR converts the image of text into actual, machine-readable text, allowing you to easily search for keywords, names, dates, or any other information. This is incredibly useful for large documents, archives, and research. Editability: Once OCR is applied, the text within the PDF becomes edita…  ( 39 min )

Responsive design isn’t a luxury anymore—it’s a necessity. In 2025, with countless devices and screen sizes, building flexible layouts that adapt beautifully is table stakes for any frontend developer. But which layout technique should you use? CSS Grid, Flexbox, or the new player in town—Container Queries? In this post, I’ll walk you through the differences, strengths, and ideal use cases of each. We'll even look at examples where they shine, and when to combine them. 🎯 1. CSS Flexbox: For One-Dimensional Layouts ✅ Pros Great control over spacing and alignment Powerful with gap, justify-content, and align-items 🛑 Limitations 💡 Example: Horizontal navigation bar .nav { display: flex; justify-content: space-between; align-items: center; } 🧱 2. CSS Grid: For Two-Dimensional Layouts ✅ Pros Supports named lines, grid areas, and implicit/explicit rows Cleaner markup than deeply nested Flexboxes 🛑 Limitations Can be overkill for simpler UI 💡 Example: Responsive 3-column layout .grid-container { display: grid; grid-template-columns: repeat(auto-fit, minmax(200px, 1fr)); gap: 1rem; } 🔍 3. Container Queries: The Future of Truly Modular Components ✅ Pros Perfect for design systems Solves the "component breaks in different layouts" problem 🛑 Limitations Requires enabling contain and setting container type 💡 Example: Card layout adapting to container size .card { container-type: inline-size; } @container (min-width: 500px) { .card { flex-direction: row; } } 🛠️ When to Use What? Use Grid for the page layout Flexbox inside each section/card Container Queries to make each card responsive on its own Understanding how to use CSS Grid, Flexbox, and Container Queries together helps you build scalable, modular, and beautiful layouts. ✍️ Over to You Have you started using container queries in your projects?

Image generated using DALL-E As I start my next college class, Introduction to Information Security, I’ve had a wake-up call: Most people—even those who use the internet every day—know almost nothing about their own home Wi-Fi. They get internet service from a provider, the installer hands them a router, and they just…start browsing. The password? Usually the default one printed on the sticker—never changed, never thought about again. Reading through my classmates’ responses this week, I saw a pattern: “I didn’t realize how much I was lacking when it comes to securing my time online.” And it hit me: If adults don’t understand the basics of the hardware and networks they rely on, how can we expect our kids to grow up safe and smart online? It’s not enough to teach kids how to avoid suspicious links or choose strong passwords. We need to teach them: How a router works Why you should change default passwords What encryption is and why it matters How devices connect to Wi-Fi and share data Understanding the hardware and connections gives them power—so they don’t just use tech blindly, but know what’s happening under the hood. Our kids aren’t just watching YouTube and doing homework online—they’re building habits that will stick with them for life. If we teach them now how to: Secure their devices Recognize insecure networks Question the default settings they’re given We’re giving them tools to protect themselves in an increasingly connected world. Did you grow up learning how your own Wi-Fi or devices worked? What have you taught your kids (or wish you had) about tech safety? How can we make understanding the basics of our devices as normal as teaching kids how to ride a bike? If we want the next generation to thrive online, we need to start by teaching them what’s happening offline—right at home.  ( 4 min )

In the ever-evolving world of cybersecurity, one thing is clear: hackers don’t send warning emails. The notion that cybercriminals will give you a heads-up before launching an attack is not just naive—it’s dangerous. In reality, the most damaging breaches often occur without any prior notice, leaving organizations scrambling to mitigate the fallout. This is why proactive measures like vulnerability scanning, penetration testing, and continuous monitoring are no longer optional—they are essential. Why Cybersecurity Should Be Your Priority Financial damage is real. Data breaches cost businesses millions every year—not just in recovery expenses but also in lost customer trust.

Today took a first step towards learning Data Science. In Python, we learned about few methods like print(),id() etc, and about Mutable & Immutable variable types. Method Print() Syntax: Method id() Syntax: Variable always refers to the memory reference and not to the value. Variable type like Integer, float and Boolean are of Immutable Type. In Immutable variable type value cant be changed and only one instance of memory is created but shall be referred to with n number of variables. Variable types like Strings, Lists are Mutable, meaning could be changed. Data structure type List: Syntax: As mentioned above in the list data structure a list of values could be stored in an order and could be referred to a particular value by indexing, index 0 refers to the first value in the List and progressively 1,2,3 etc refers to the next consecutive values.

Building a React component library that puts developer experience and customization first Picture this: You're building a beautiful accordion component for your app. You want to add some smooth GSAP animations to make it feel premium. You're using shadcn/ui, which is fantastic, but then you hit a wall. The accordion component uses Radix UI primitives under the hood. These primitives are great for accessibility and basic functionality, but they're black boxes. You can't modify their internal behavior. You can't add complex animations. You can't change how they handle state transitions. I needed my accordion to have sophisticated GSAP animations with custom easing, staggered reveals, and precise timing control. But the Radix primitives were fighting me every step of the way. That's when I re…  ( 6 min )

This post is my submission for DEV Education Track: Build Apps with Google AI Studio. I set out to build an AI-powered interior design app that generates realistic room images based on user inputs like room type, style, color theme, and special features. I used Google AI Studio with Imagen for image generation, Gemini for collecting user data, and built the frontend with React, TypeScript, and Tailwind CSS; additional features include image download, share options, and a history of generated results. Here is the prompt I used in Google AI Studio: Create a React + TypeScript + TailwindCSS app that generates realistic interior design images using Google Imagen based on user-selected room type, style, color theme, and optional features, with Gemini-assisted input, image download, sharing options, and generation history. Github URL Working through the track, I learned how to effectively integrate Google’s AI tools—Imagen and Gemini—into a real-world application, especially how prompt design directly impacts the quality of generated images. I was surprised by how smoothly Gemini handled structured data collection and how Imagen could generate visually compelling results with just a few key parameters, making complex design generation accessible with minimal user input.  ( 3 min )

The term "coroutine" often comes up when talking about asynchronous or non-blocking code, but what does it actually mean? In this post, we will explore coroutines as a concept and see how PHP supports them through Generators and Fibers. Whether you're building pipelines, CLI tools, or preparing to dive into concurrency, understanding coroutines is an essential first step. A coroutine is a function. However, where a regular function continuously runs from top to bottom until it is finished, a coroutine can pause/suspend itself and be resumed. It can return a value every time it suspends, and receive a value when it is resumed. While the coroutine is suspended and not yet finished, it will hold on to the current state it is in. Once a coroutine is executed, it will start performing its task.…  ( 15 min )

We speak, we write, we connect. But what if the very words we use are subtly dictating our reality? Language, often seen as a mere tool for communication, possesses a hidden power — a power so immense it shapes our thoughts, beliefs, and even our understanding of the world. And its true complexity is almost always ignored. What are words? They’re a bunch of syllables that are attached to an object or idea. Words have complicated meanings and carry the burden of context and historical usage.

Introduction Modern frontend tooling gives us so many options: SSR, CSR, SSG, ISR, edge functions, etc., and it’s easy to get caught up in what’s trending. I’ve seen teams jump onto SSR just because it sounds “enterprise” or go full SPA without thinking through the SEO or performance impact. The truth is: every rendering strategy is a trade-off. In fact, that's the First law of Software Architecture, "Everything is a trade-off". SSR can solve specific problems really well, especially around SEO, performance, security, and network optimization. But, it also comes with operational overhead (think server cold starts, caching strategies, latency tuning, etc.). So, before you adopt it, understand what you're solving. In this post, I’ll walk through the use cases where SSR helps and where CSR …  ( 6 min )

Problem Statement You are given an array arr[] of integers. Your task is to find the maximum sum of the smallest and second smallest elements across all subarrays (of size >= 2) of the given array. Examples : Input: arr[] = [4, 3, 5, 1] 2 ≤ arr.size() ≤ 10^5 Instead of iterating through all possible subarrays and finding the smallest and second smallest elements (which is inefficient), we can simplify the problem using the following observation: To maximize the sum of the two smallest elements in a subarray, both of them should be as large as possible. This naturally leads us to a key insight: Among all subarrays of size ≥ 2, the ones with only 2 elements are sufficient to check. Why? Because: In a longer subarray (size ≥ 3), the two smallest elements tend to be smaller, hence their sum is also smaller. With just 2 elements, we know the smallest and second smallest directly — it's just the two numbers themselves. Initialize a variable maxSum to 0. Loop through the array and for every adjacent pair, calculate their sum. Update maxSum with the maximum of the current sum and the existing maxSum. Return maxSum at the end. Time Complexity: O(N) where N is the length of the array. class Solution { public int maxSum(int arr[]) { if (arr == null || arr.length == 0) { return 0; } int maxSum = 0; int length = arr.length; for (int index = 0; index < length - 1; index++) { maxSum = Math.max(maxSum, arr[index] + arr[index + 1]); } return maxSum; } }  ( 4 min )

Building robust conversational AI systems often requires solving two foundational issues: Gracefully handling missing or incomplete user input (e.g., “Add 3” instead of “Add 3 and 4”). Suppose you’ve deployed an OpenAI-based assistant that can perform arithmetic via a tool function. A naive implementation might fail when a user omits arguments (“Add 3”), or even worse, the model may hallucinate — making up numbers or answers. We want: The system should prompt for any arguments it needs. If clarification is needed, interactively get it from the user, instead of letting the model guess. Using LangChain’s agent system, you can wrap business logic (say, a Python function) as a first-class tool. Structured input models allow you to enforce argument schemas (with Pydantic), making it easy to cat…  ( 5 min )

Today's Progress After several iterations, the seasonal logic refactor and purchase section structuring have finally reached a level I’m genuinely satisfied with. Here’s what I accomplished: Clearer Purchase Options via Tabs The purchase section now uses tabbed navigation to clearly separate: Immediate shipment Scheduled delivery Subscription (regular delivery) This allows users to see only the information relevant to them, reducing cognitive load and keeping the UI cleaner. I believe this offers a much more user-friendly experience, especially given the complexity of the purchasing process. Multi-Site Handling: Avoiding Info Overload There are 4 different ec platforms involved, each with unique: Product offerings Pricing Shipping fees Service levels Rather than overwhelming users with all this at once, I chose to simplify the display logic. Only key differences are shown depending on user interaction, keeping the content digestible. Image Organization: Rule-Based Refactoring I introduced a consistent image file organization rule All images are placed into folders named after their section (e.g., /action, /hero) Filenames start at 001 Shared assets like background textures or borders are exceptions This small change helped keep the project organized and reduces errors when referencing assets. Action Section Refactor: Split, Break, Fix I attempted to split the overly long ActionSection tags: nextjs, frontend, portfolio, typescript, ux  ( 3 min )

If you’ve ever been confused by AWS terms like AssumeRole, STS, and Trust Policies, you’re not alone. Here’s the simplest way to understand them — using something we all recognize: ID cards, employees, and security desks. Think of AWS like a secure building. Inside this building are restricted areas like: 📦 A storage room (S3) 🔐 A vault (Secrets Manager) 🧾 A database office (DynamoDB) To get into these areas, you need an ID card with the right permissions. 🧾 IAM Role = ID Card “Whoever holds this card can access the storage room and the vault.” It doesn’t belong to a specific person — but it has permissions attached to it. 👨‍💼 Principal = Trusted Employee For example: An EKS Pod A Lambda function An IAM User The Trust Policy defines which employees are trusted to borrow the card. 🛡️ STS (Security Token Service) = Security Desk When a trusted employee (e.g., an EKS pod) walks up to the security desk and says: “I’d like to assume the StorageAccess role,” STS checks the Trust Policy: Is this pod allowed to use this role? ✅ If yes → STS gives the pod a temporary ID card ⏱ That ID card works for 15 minutes to 1 hour (short-lived credentials) 🔄 Real-Life Flow 🧑 An EKS pod starts up and wants to access S3. 📇 The pod uses its service account to ask STS to assume a role. 🛡️ STS checks if the pod is a trusted principal. ✅ If allowed, STS gives the pod temporary AWS credentials. 🔐 The pod uses these credentials to access S3, DynamoDB, etc. 📌 Quick Summary Table Understanding IAM roles becomes easy when you think in real-world terms. “It’s like borrowing an ID card from security to access a room you’re allowed into — but only temporarily.”  ( 4 min )

"Sometimes, the most powerful tools aren't shiny frameworks, but silent design decisions." If you're still tightly coupling your UI with your backend, you're probably wasting time and limiting reusability. I discovered this the hard way — until I stumbled upon headless architecture. Not through a textbook. Not from a YouTube guru. But from trying to automate a stubborn legacy system. This post is about that journey — and why headless design might be the underrated gem you're not using enough. Headless architecture is a decoupled design where the backend logic is independent of the frontend UI. You can trigger services, logic, or workflows without needing a UI to exist or be loaded. UI optional, logic unstoppable. I was building a financial statement distribution system using C# and Windo…  ( 4 min )

Hey array detectives! 🔍 Today we’re tackling a charming problem that blends frequency counting and a bit of luck. The idea? Identify integers in an array whose value matches their count. These are called lucky integers — and our goal is to find the largest one! Let's dive into the logic and crack the problem in all three major languages. 🎯 You're given: An array arr of integers. Your goal: Return the largest lucky integer in the array. An integer is considered lucky if its frequency in the array equals its own value. If no such integer exists, return -1. We simply need to: Count the frequency of each number in the array. Check which numbers have frequency equal to their value. Return the largest such number. Since values are capped at 500, we can use a frequency array for efficient counting. class Solution { public: int findLucky(vector& arr) { vector count(arr.size() + 1); for (const int a : arr) if (a = 1; --i) if (count[i] == i) return i; return -1; } }; class Solution: def findLucky(self, arr: List[int]) -> int: from collections import Counter count = Counter(arr) res = -1 for num, freq in count.items(): if num == freq: res = max(res, num) return res var findLucky = function(arr) { const freq = new Map(); for (const num of arr) { freq.set(num, (freq.get(num) || 0) + 1); } let res = -1; for (const [num, count] of freq.entries()) { if (num === count) { res = Math.max(res, num); } } return res; }; Use frequency maps or arrays to track counts. Look for numbers where value == frequency. Always return the largest such number (or -1 if none). This problem is a great exercise in hash maps and frequency counting. Simple, clean, and a great fit for coding interviews or warmups. Keep the code flowing, and see you in the next breakdown! 🚀  ( 4 min )

This post is my submission for DEV Education Track: Build Apps with Google AI Studio. I was tired of bloated webapps for practicing system design problem or creating one.

Working with data is often about solving complex problems, generating insights, or finding patterns. But behind every powerful dashboard or predictive model, there’s a quiet yet essential process taking place: cleaning and preparing the data. Among the earliest and most important tasks in this process is renaming columns. In Python’s Pandas library, this is commonly referred to as “pandas rename column”—a deceptively simple term for a step that can have a major impact on your project. When used correctly, renaming columns transforms messy, unclear data into something meaningful, accessible, and ready for analysis. In business terms, it means faster workflows, fewer errors, and more confident decision-making. Why Renaming Columns Is a Strategic Move Renaming columns aligns your dataset with…  ( 6 min )

Well, not quite. Every time I tried this setup, I ran into a Bicep linting error. More importantly, I was uneasy about the fact that the storage account key would always be exposed in the deployment output. Anyone with access to the deployment history could easily view it under: Resource Group → Settings → Deployments Here’s what that looks like: T…  ( 4 min )

Durante más de tres décadas, la categoría Computer Systems Analyst (CSA) de la visa TN ha sido una de las rutas más directas para que un buen número de devs mexicanos se fueran a trabajar a Estados Unidos. Sin lotería, sin cuotas anuales como la visa H1-B, y con requisitos relativamente sencillos. Bastaba tener una oferta, un título o experiencia, y entrar bajo esta categoría. Aunque la descripción decía que era para "analistas de sistemas", la verdad es que era un secreto a voces que muchas personas entraban como CSA para trabajar como programadores. Eso acaba de cambiar. Esta semana, el Servicio de Ciudadanía e Inmigración de EE.UU. (USCIS) publicó una actualización a sus políticas donde pone las cosas algo más complicadas: “While systems analysts may perform some programming, this category does not include programmers.” — USCIS Policy Manual – uscis.gov Si tu trabajo es principalmente programar, ya no calificas bajo la visa TN como CSA. “An engineer may not fill computer-related jobs unless he or she has credentials as a computer or software engineer in a bona fide engineering specialty offering full engineering credentials, such as professional engineering licenses.” USCIS Policy Manual – uscis.gov Es decir, no basta con que tu título diga "Ingeniero". El puesto tiene que requerir conocimientos de ingeniería formal. Antes, la categoría de System Analyst era bastante laxa, y muchos la usaban para entrar siendo devs. Ahora, el mensaje es claro: si programas, esta categoría (CSA) ya no es para ti. Y la categoría de “Engineer” tampoco es segura, a menos que cumplas requisitos muy específicos. Si ya tienes una visa TN, puede ser buen momento para hablar con tu empresa o tu abogado de migración. Asegúrense de que la descripción de tu puesto no te ponga en problemas al renovar. Si estás aplicando a nuevas vacantes y esperabas usar una TN, quizá ahora la ruta sea la H1-B, que aunque tiene cuotas, lotería y es más tardada, al menos no hay problema para programadores.  ( 4 min )

When I started working with FastAPI, I quickly realized one thing: A messy project becomes hard to scale, hard to maintain, and hard to debug — especially when you’re working on real-world APIs or collaborating with a team. Over time, I settled on a project structure that keeps things organized, clear, and ready to grow. In this post, I’ll walk you through the structure I use and why it works for me. ⸻ 🗂 FastAPI Project Structure Example Here’s what my folder structure looks like for a typical FastAPI project: app/ ├── admin/ → Admin operations (separate logic for admins) ├── models/ → SQLAlchemy database models ├── schemas/ → Pydantic request & response schemas ├── crud/ → Database operations (clean, reusable functions) ├── routes/ → API endpoints, cleanly separated by feature ├── core/ → Auth logic, password hashing, reusable dependencies ├── database.py → Database connection & session setup ├── config.py → App settings & environment variables alembic/ → Database migrations (optional, recommended) env/ → Virtual environment folder (optional) .env → Secrets like DB URI, JWT keys requirements.txt → Project dependencies 💡 Why I Like This Structure ✔️ Separation of Concerns — Each folder has a clear responsibility 📦 Quick Notes on Key Folders ✅ Conclusion A clean project structure won’t solve all your problems — but it definitely saves you time and headaches down the road. This structure works for me on both small and growing FastAPI projects, and I’m always open to improving it. How do you structure your FastAPI apps? I’d love to hear your suggestions, ideas, or different approaches in the comments! 🙌 fastapi #python #webdev #backend #projectstructure #softwarearchitecture  ( 4 min )

Hey Developer Community! 👋 Wir müssen reden – über Clean Code.

We thought we were just getting a faster way to work. We got a new creative partner that’s changing everything. Guessing Games: We could no longer predict how long a task would take. A simple job could be done in 5 minutes if the AI knew exactly what to do. But a slightly more complex job could take days of fixing the AI's weird mistakes. Our neat to-do lists and deadlines became meaningless. Strange Mistakes: When a human makes a mistake, you can ask them why. You can trace their logic. When the AI makes a mistake, there’s no "why." It just blended two ideas from its vast library of knowledge that shouldn't have gone together. Fixing it feels like solving a bizarre puzzle. This Isn't Scary, It's an Opportunity Some people see this change and get nervous. They see a loss of control. I see the biggest business opportunity of our lifetime. The companies that thrive will be the ones that master this new partnership. They will build teams of great "storytellers" and "editors" who can direct AI to create amazing things at unbelievable speeds. Imagine launching a new product in a week instead of a year. Imagine testing a new marketing idea in an afternoon instead of a month. This is the future of work. It’s less about the robotic process of a factory assembly line and more about the creative collaboration of an artist’s studio. And frankly, it's making our jobs more human, more creative, and more exciting than ever before.  ( 4 min )

This is a submission for the World's Largest Hackathon Writing Challenge: Beyond the Code.

Kafka as a Distributed Log: A Deep Dive for Data Platform Engineers 1. Introduction The relentless growth of data volume and velocity presents a constant challenge for modern data platforms. We recently faced a critical issue at scale: real-time fraud detection requiring sub-second latency on a stream of 10M events/second. Existing batch pipelines, even with Spark Streaming, couldn’t meet this requirement. Furthermore, the need for historical analysis and model retraining demanded a durable, replayable data source. This led us to a deeper investment in Kafka, not just as a message queue, but as a foundational distributed log for our entire data ecosystem. Kafka’s ability to decouple producers and consumers, provide ordered event streams, and support replayability is crucial when integ…  ( 7 min )

This is a submission for the Runner H "AI Agent Prompting" Challenge I created a prompt for Runner H that generates a beginner-friendly, text-based network diagram of a home lab, clearly labeling devices such as a router, switch, firewall, and three computers to help visualize basic network topology. Additionally, it produces a simple Python script that pings each device and outputs a status report indicating which devices are online or offline, with detailed comments explaining each part for easy understanding. Finally, the prompt includes a fun Star Wars-themed analogy that describes how this script acts like checking the "shield generators" to maintain the health of the network. This solution addresses the challenge of making networking concepts accessible and engaging for beginners, pa…  ( 4 min )

Hey there 👋 I’m Yassine Qoraiche, the founder of SleekSaaS and creator of MailEclipse, an open source email editor trusted by thousands of developers. Over the years, I’ve built and shipped multiple SaaS products — and I’ve felt the pain of rebuilding the same foundational features over and over again: authentication, billing, admin panels, SEO, localization, dashboards...

In modern DevOps, immutability is a cornerstone of both security and reliability. Docker makes it straightforward to enforce immutability by mounting the container’s root file system as read‑only. This prevents any runtime modification—accidental or malicious—of the files baked into the image. This lab‐style guide shows you how to: Build a minimal image. Launch a container with a read‑only root. Prove—both manually and programmatically—that it really is read‑only. Why lock the root file system? Defense in depth – Attackers (or faulty scripts) can’t tamper with binaries or libraries. Operational consistency – Every container instance is bit‑for‑bit identical to the image. Stateless architecture – Ideal for workloads where state lives in external services, volumes, or databases. Scena…  ( 4 min )

Introduction What is last mile delivery and what are its benefits for businesses and consumers alike? One of the biggest benefits of last mile delivery is that it can help to improve customer satisfaction. By ensuring that goods are delivered directly to the customer's door, businesses can avoid missed deliveries and delays. In addition, customers can track their orders and receive real-time updates on the status of their delivery. This transparency helps to build trust and loyalty between businesses and consumers. Another benefit of last mile delivery is that it can help businesses to reduce costs. By optimizing routes and using smaller vehicles, businesses can save money on fuel and labor costs. In addition, by collaborating with other businesses in their area, businesses can share resou…  ( 5 min )

7 days of work has gone into this. COMMIT YOUR FUCKING CODE PEOPLE! This is a good time to recap and reflect. Right that's one bit of reflection. I've not commited in 7 days and today.. the fucking day I was gonna do a little recording and intro to the current game. Gemini went and bummed me hard and broke everything. Burnout++. Today will be a bit of a easy day (optimistic fucker). Yesterday got a little toasty on the burnout scale (extra toasty today). Finished stripping the save mechanics.

Introduction When working with sensitive data in SSIS, understanding and configuring the ProtectionLevel setting is essential for maintaining security throughout your ETL process. Open your SSIS project in SQL Server Data Tools (SSDT) or SQL Server Management Studio (SSMS) Right-click the project (or an individual package) and select Properties In the Properties window, locate the ProtectionLevel option This setting defines how sensitive information (like passwords or connection strings) is stored and secured. DontSaveSensitive Sensitive values are removed and not saved. EncryptSensitiveWithUserKey Data is encrypted using the current user’s credentials (not portable). EncryptSensitiveWithPassword Sensitive data is encrypted using a specified password. EncryptAllWithPassword The entire package is encrypted with a password. EncryptAllWithUserKey Entire package encrypted with the current user key (rarely used). ServerStorage Only used in SSISDB deployments; protection is handled by the server. Use DontSaveSensitive for automated CI/CD pipelines or server deployments. Use EncryptSensitiveWithPassword when sharing packages between developers. Avoid user-based encryption (EncryptSensitiveWithUserKey) if you need portability. For a complete walkthrough with UI screenshots and additional tips: 👉 Read the full guide here  ( 3 min )

This post is my submission for DEV Education Track: Build Apps with Google AI Studio. I built ClosetAI, a smart wardrobe and outfit planner app that helps users digitize their clothing, track wear history, and get AI-powered outfit recommendations based on weather, calendar events, and mood. "Create an app that digitizes a user's wardrobe using photos and classifies clothing items." "Generate daily outfit suggestions using AI based on weather and user calendar." I also integrated features like wear tracking, sustainability reminders, and weather API integration. App Link ----> https://aistudio.google.com/app/prompts?state=%7B%22ids%22:%5B%221If8jfU-t3ZOSX4cu4_DgJmUg2ZZCiIk-%22%5D,%22action%22:%22open%22,%22userId%22:%22105223628317172329930%22,%22resourceKeys%22:%7B%7D%7D&usp=sharing Working on this project taught me a lot about combining computer vision with AI-driven personalization on mobile platforms. I learned how to use image classification models (TensorFlow Lite) on-device for fast processing and how to integrate weather and calendar APIs for contextual suggestions. It was surprising how well AI can assist in everyday decision-making like picking an outfit, and the importance of designing simple but effective UI for non-technical users.

🤯 "Prompts are no longer throwaway lines — they’re becoming architecture." In 2023, prompt engineering felt like a clever hack. In 2025, it's something else entirely. More and more developers are treating prompts like code assets — versioning them, testing them, and sharing them across teams. It’s no longer just about writing a smart sentence for ChatGPT. It’s about designing structured prompt logic that powers core application behavior. And the tool that’s enabling this shift? 👇 Prompt Libraries. Is a Prompt Library? You’re not alone if that phrase makes you pause. We did too — until we dug deeper. A prompt library isn’t just a folder of copy-paste prompts. It’s the next evolution of how we architect intelligent software. Instead of writing brittle prompts scattered across your app……  ( 4 min )

🧠 Today’s Focus As Lura evolves into more than just a case and document management platform, I wanted to explore how we can make it feel intelligent — like it’s working with you, not just for you. That led me to deepen my integration of Dify and Ollama, specifically around prompt engineering. While I had Dify running earlier in the project, today was about quality — not just functionality. 🧩 What I Worked On 1.Refining Prompt Templates: Instead of using a generic prompt like “Summarize this document,” I wrote a more tailored version: You are a legal assistant AI inside a document platform. Always summarize in simple language, highlight important names, and suggest next steps for legal actions.

JavaScript's Asynchronous Execution: V8 and the Event Loop Abstract JavaScript's asynchronous behavior is a cornerstone of its power, enabling non-blocking code in a single-threaded environment. Constructs like setTimeout, Promise, and async/await are widely used, yet their internal mechanisms remain opaque to many developers. This article explores the interplay between the V8 JavaScript engine (version 12.5 as of 2025) and the Event Loop, facilitated by libuv in Node.js or Blink in browsers, through internal C++ interfaces. We aim to clarify how the Call Stack, Event Loop, Task Queue, and Microtask Queue collaborate, and detail how V8 handles asynchronous code execution, with practical examples and performance insights. JavaScript operates on a single thread but supports asyn…  ( 7 min )

Introduction Training GPT-4 reportedly cost OpenAI over $100 million, while a single inference request can cost several cents—costs that quickly add up for developers building AI-powered applications. Today's AI landscape is dominated by a handful of tech giants who control the infrastructure, pricing, and access to artificial intelligence computing power. This centralization creates significant barriers for innovation, particularly for smaller developers and organizations in developing regions. ** ** ** *Decentralized AI inference promises transformative effects across multiple domains, particularly for underserved markets and innovative applications. Conclusion ** Decentralized AI inference represents a fundamental shift toward democratizing artificial intelligence capabilities. By distributing computational resources across independent networks, this approach addresses the current limitations of centralized AI infrastructure while creating new opportunities for innovation and economic participation. The technology's success depends on overcoming technical challenges while building sustainable economic models that benefit all participants. As the ecosystem matures, decentralized AI networks have the potential to transform how we access and deploy artificial intelligence, making these powerful capabilities available to developers, researchers, and organizations worldwide. For developers considering this technology, the opportunity exists to both contribute to and benefit from this emerging infrastructure. Whether by operating nodes, building applications, or simply using decentralized AI services, participants can help shape a more accessible and equitable AI future while advancing their own projects and goals. The democratization of AI through decentralized inference is not just a technical advancement—it's a step toward a more inclusive digital economy where innovation can flourish regardless of geographic location or economic circumstances.  ( 7 min )

In the world of concurrent systems, data consistency is both a challenge and a priority. When multiple clients try to read and write to the same resource—say, a Redis key—without coordination, things can go wrong fast. This is where locking comes in. But not all locking is created equal. Optimistic locking is a concurrency control method that doesn’t lock the resource immediately. Instead, it watches it for changes and performs a check right before committing any updates. If someone else modified the resource in the meantime, your update gets rejected, and you can try again. The core idea is: “Let me do my work assuming no one else will interfere, but I’ll double-check before saving.” Redis is a blazing-fast, in-memory data store—often used in highly concurrent environments. Traditional lo…  ( 4 min )

Most AI agents hit a wall at 70-80% functionality. They demo well, but when it comes to production, they fall apart. After analyzing 100+ production agent implementations, a clear pattern emerged: the most successful agents aren't the most "agentic" — they're well-engineered software systems that leverage LLMs for specific, controlled transformations. You've probably experienced this: You wire up a framework, get to 70-80% functionality quickly, and everyone's excited. Then reality hits. That last 20% becomes a debugging nightmare. You're seven layers deep in abstractions, trying to understand why your agent keeps calling the wrong API in an infinite loop. The truth? Agents are just software, and the teams succeeding with them understand this fundamental principle. Here's a quick overview …  ( 5 min )

Title: Modern Day vs. Olden Days – Which Era Wins? Introduction: Every generation looks back at the past and compares it with the present. Some say the olden days were better—life was simpler, people were kinder, and values were stronger. Others argue that the modern day is far more advanced, convenient, and full of opportunities. So, who’s right? The Olden Days: The olden days were filled with community spirit and natural living. People farmed, fetched water from wells, and respected elders deeply. There was little or no technology, but there was peace, contentment, and strong cultural values. Families spent time together, and children learned from folktales, not smartphones. The Modern Day: In today’s world, we have fast internet, smartphones, airplanes, online learning, and medical breakthroughs. Life is more convenient—meals can be ordered, money sent in seconds, and we can talk to someone in America from our living rooms. But with all these, modern life comes with pressure, isolation, and moral challenges. The Balance: While the olden days gave us wisdom and strong values, the modern day brings innovation and speed. The truth is, each era has its strengths and weaknesses. What we need is to combine the good of both worlds—preserve the respect and values of the past while embracing the benefits of the present. Conclusion: Whether you admire the past or enjoy the present, one thing is clear: it is our actions today that will determine how the future sees our time. So, let us learn from the old, make use of the new, and build a better tomorrow. 🗣️ Which side are you on—Olden Days or Modern Day? Share your thoughts!  ( 3 min )

Introduction "Why is it that I can’t seem to focus at home, yet somehow I’m productive at a café?" Personally, I’ve often taken my laptop to work outside—at cafés, libraries, or other public spaces. But I could never clearly explain why I struggled to focus at home, and why putting in the extra effort to go out seemed to help me get more done. Recently, I happened to look into this phenomenon and discovered that it’s not just a matter of mood or superstition. In fact, scientific research has shown that the brain's ability to focus is deeply influenced by the quality of background noise. In 2012, Professor Ravi Mehta from the University of Illinois, along with his colleagues, published a paper titled “Is Noise Always Bad?

Ever had an AI assistant confidently tell you “bug fixed!” several times… only to discover the bug is still alive and kicking? I sure did. I was fighting a stubborn UI glitch in the macOS tray menu of my side-project. Using Cursor, I followed my normal routine: describe the bug in detail, list the steps to reproduce it, and spell out the expected behaviour. I threw every model I had at the issue—Claude-4 Sonnet, Gemini 2.5 Pro, GPT-4.1 and even attached screenshots. Each model rewrote different parts of the code and proudly announced “Fixed!”. But when I ran the app, the bug was still there. Worse, the AI sometimes got stuck in loops or removed unrelated features in its attempts to “help.” After a few hours, I realised I was spinning my wheels. Instead of letting the AI rewrite code, I set one hard rule: the AI can only add debug logs—nothing else. Restrict AI permissions – “Add log lines only.” Get targeted grep commands – the AI supplies copy-ready commands after every change. Feed real data back – run the app, reproduce the bug, paste the filtered logs into chat. Repeat until breakthrough – short, focused iterations. After 4–5 loops, we traced the culprit to bad cache invalidation in the data layer—nowhere near the UI. One tiny manual patch fixed everything.

When I started in SRE, I knew Linux, AWS, and had a vague idea of “monitoring.” But it wasn’t until I got thrown into a few 5 AM incidents that I realized just how critical some tools and habits are. Here’s a look into the toolkit I wish I had mastered earlier, especially if you’re working with AWS-native infrastructure. 🟢 1. CloudWatch: The Silent Sentinel CloudWatch Alarms for thresholds on CPU, disk, memory, latency. 🚨 2. PagerDuty: Alert Me, But Nicely 🌐 3. StatusPage: Letting the World Know (Calmly) StatusPage can help us: 💡 Pro Tip: Ask your users to subscribe to statuspage, this will alert them timely, and they can keep track of issue. 🛠 4. Terraform (and CloudFormation): Infra As You Code It 📦 My stack: Tools like tfsec, checkov, and pre-commit for validation. 🧑‍💻 5. Linux & SSH: Still the Last Resort What I keep in my toolbox: 🎯 Wrapping It Up You don’t need a huge team to be reliable — you just need to be intentional about visibility, ownership, and communication. 💬 What’s in Your Starter Pack?

I'll cut to the chase because I know this isn't the most original topic. I have been thinking about AI and decided to gather some of my thoughts together. First I have to point out how cool of a world we now live in. Generative AI may seem normal by now, almost mundane. But when I step back and try to look at it from a fresh perspective, it's the most spectacular and unexpected technology of my lifetime. In early 2022, if you had showed me Claude Sonnet 4 iteratively implementing a feature while writing tests in Cursor and asked me to predict when such technology would be invented, I would have guessed the 2040s at the earliest. Yet here we are just a few years later in 2025. A lot of Sci-Fi AIs suddenly look plausible with current technology. HAL 9000 from 2001: A Space Odyssey, the term…  ( 8 min )

This has bugged me for a while, so I asked GPT. What have you heard of design principles in the object orientation space. I generally subscribe to encapuslation and keeping data with the behaior, but with years of experience I see cracks in the wall, specifically regarding the tension between "what should know HOW to do something" (answer clearly being the appropriate object) VS "what should know when and what messages to dispatch to what objects" (answer being less clear if we have public methods on objects). I think record creation stands out as a prominent special case where encapuslation does not quite work. For example, I have a nesting of models Parent -> (many)Child. And I need a versioning/copying functionality for the aggregate. I do not think Child should know anything about dupl…  ( 5 min )

50 Users. 1 Submission. 0 Votes. What I Learned. I launched VibeFight.com a few days ago — a daily arena where small projects (tools, games, websites) get submitted, and one wins each day based on votes. The idea: Only 20 can launch per day No visible vote counts (to prevent bias) You vote for one project using its ID The winner gets featured the next day 50+ people visited within the first few hours Dozens said the idea was genius Only 1 person submitted 0 votes were cast That disconnect was loud. People lurk — especially early on If there's nothing to engage with, most people just leave.

This post is my submission for DEV Education Track: Build Apps with Google AI Studio. I created BrandSpark, a web app that leverages Google Gemini and Imagen models (via Google AI Studio) to generate complete branding kits in seconds. Key prompt used: “Create an app which uses Al to generate unique logos and branding descriptions for businesses, projects, and teams. Users provide details and receive a custom logo and tagline created by Gemini.” Additional features: Choice of logo styles (Modern, Retro, Geometric, etc.) Predefined color palettes (Vibrant, Earthy, Monochromatic, etc.) Downloadable PNG assets and persistent local state Here’s a quick look at BrandSpark in action: Also you can check out the website at: BrandSpark Working through the Build Apps with Google AI Studio track taught me: Seamless API Integration: How to structure requests to Google Gemini for text‑based prompt engineering. Chaining responses into Gemini model calls for high‑quality image outputs. Prompt Engineering Nuance: Small tweaks in phrasing dramatically affected logo composition and color balance. Iterating on prompts led to much crisper, on‑brand visuals. State Management & UX Considerations: Saving user inputs/results in localStorage made the experience frictionless. Implementing spinners and error messages ensured smooth, transparent feedback. What surprised me most was how quickly the AI iterated on dozens of design variations—the combination of Google’s large‑language and image models felt truly magical. This project sharpened my full‑stack skills (React, Vite, Tailwind) while deepening my understanding of modern generative‑AI workflows.  ( 3 min )

Collecting internal and external data along with further analysis and insights’ extraction simplifies real-time decision-making. In 2025, the main competitive advantages are not about accessing information, but getting and leveraging it before competitors.

When designing business-critical systems in Rails, we often begin with clear and concrete concepts. A model like WorkLog—which records completed work tasks—can seem straightforward at first. However, applying Domain-Driven Design (DDD), particularly Actor Analysis, can uncover subtle complexities that have significant architectural implications. In a recent project, a WorkLog model was implemented to track task completions. At a glance, the model served a singular purpose: record work performed by employees. However, Actor Analysis revealed that two distinct groups interacted with this data in markedly different ways: Workers needed to log their tasks quickly and occasionally update entries as corrections arose during the workday. Quality Checkers, on the other hand, reviewed the same Wo…  ( 4 min )

Using attr() function Here's the syntax: element { property: attr(data-attribute-name); } For example, if you have an HTML element like this: )); /*add type() as it is, to tell browser that type of value is a type of color*/ font-size: attr(data-font-size px)} } .html Visit W3Schools Solution 2: You can also use CSS custom properties (variables) to achieve this. For example: div { background-color: var(--color); } This way, you can dynamically set the value of the --color property and it will be used in the CSS. Note: that the attr() function is not widely supported for all properties, and it's mainly used for the content property. For other properties, you may need to use other approaches like attribute selectors or custom.  ( 3 min )

How I built client-side AES-256-GCM encryption for GHOSTVAULT in 72 hours When I started building GHOSTVAULT during the World's Largest Hackathon, I had a simple requirement: true zero-knowledge architecture. Not the marketing buzzword kind, but the real deal — where even I, the creator, cannot access user data. After 72 hours of intense development, I learned that implementing real zero-knowledge encryption isn't just about choosing the right algorithm. It's about solving problems that crypto tutorials never mention: How do you derive keys securely from passwords? What happens when users choose weak passwords in a zero-knowledge system? How do you handle encryption failures gracefully? How do you make security user-friendly? This series covers the real implementation challenges I faced bu…  ( 7 min )

In this, we will check out 3 Postgres platforms you can use for free. PostgreSQL is a powerful open-source database. It supports SQL queries, making it easy to use while offering the flexibility and reliability needed for modern full-stack apps. PostgreSQL is also recognized for its robust data integrity, as the system follows the principles of Atomicity, Consistency, Isolation, and Durability (ACID). In doing so, PostgreSQL never loses, corrupts, or allows inconsistent data, which is important for applications such as banking and healthcare. Neon is a serverless, cloud-based PostgreSQL solution that separates compute and storage. This unique architecture allows Neon to autoscale compute resources based on demand, while storing data in a shared, multi-tenant key-value system. This setup is ideal for developers who want a fast, flexible, and cost-efficient PostgreSQL experience without the overhead of managing infrastructure. Neon can run on managed cloud services or physical hardware, providing teams with greater deployment flexibility. One of the features is its free tier, making it easy for developers to build and test small projects or MVPs. Aiven offers a range of open-source managed data infrastructures, including PostgreSQL, Apache Kafka, Elasticsearch, Grafana, InfluxDB, MySQL, Redis and more. Aiven supports deployment across various cloud providers, enabling users to select the best infrastructure for their specific needs. When using the free plan, you can only access one service; however, Aiven offers a 30-day free trial that allows you to access all services. Render is a more traditional hosting platform that enables you to build and deploy your applications, websites, and databases. It is an excellent choice for both seasoned developers and beginners, as you don't have to worry about using multiple platforms to host your application and database. Apart from Render’s user-friendly interface, it offers a free PostgreSQL hosting plan for development and testing, hobby projects, and MVPs.  ( 3 min )

If We Share Technology, What Kind of Future Could We Build? (Open Innovation #2) In my last post, I asked a simple question: What if innovation didn’t need to be secret? This wasn’t a rhetorical thought. It was born from a growing discomfort— watching every company race to build nearly identical models, each in isolation, consuming more power, more silicon, and more human capital—just to stay ahead by a few months. That race might be “natural” in today’s economy, but I’m starting to think it’s not sustainable, not efficient, and not inevitable. So I asked myself: If we shared technology—openly, responsibly, and with proper reward mechanisms— what might change?

After bombing a back-end developer interview, I was feeling pretty low. That’s when my friend Sospeter Mongare, a Senior Backend Developer, shared some sharp advice that hit me hard but also made me laugh. Beneath the humor of his words was a powerful truth about the importance of skill-building and consistency. His advice, born from years of experience, inspired me to turn his message into a motivational article for anyone chasing mastery in their craft. The Disconnect Between Pay and Proficiency A graphic designer who doesn’t know CorelDRAW or Photoshop, swearing by Canva as the ultimate “professional” tool.

For a long time, when I first started writing tests, I felt so unproductive writing tests. I would try to write the test as fast as possible so I could move on to the "real" code. Then one day when a production deployment failed due to missing a simple test I realized the critical value of tests, and that good tests are in fact "real" code and they do deliver immense value. I began to see tests as "support beams" for the application that prevent it from collapsing. What are good tests? Good tests are ones that fail only when there is something really wrong. Like the logic was altered unintentionally by some change. Good tests don't depend on data that might change. Good tests happen when you have complete control of all the inputs. If your test is failing when nothing is wrong then make it…  ( 4 min )

Hey devs 👋 So, I kinda… outsourced half my brain to AI. And not in a “take over the world” way—more like: “Can you write the boilerplate while I eat cereal and design the UI?” I'm Liemar, a solo dev (still a teen 💅), and I'm building a platform called Nexix—a kind of AI-powered knowledge library that gives you raw answers, not fluff. Like if Stack Overflow and Google had a baby raised by a truth-obsessed uncle. And yep, I let AI do most of the heavy lifting. Here's how. I don’t just ask AI “what’s the code for X.” I use it like a brainstorm buddy, code assistant, and therapist when TypeScript starts gaslighting me. Here’s how AI fits into my workflow: Content Generation: My platform generates full learning responses from user queries using AI. No user-submitted junk—just auto-generat…  ( 4 min )

The morning started with my immune system apparently deciding to take an unscheduled vacation, leaving me feeling like a computer running on 10% battery. But by evening, muscle memory kicked in - laptop open, fingers on keyboard, doing what I do best: pretending I know what I'm doing while actually figuring it out. So I joined a startup as a "co-founder" today. Before you get impressed, let me clarify - "co-founder" currently means "person who really hopes this completely raw idea somehow works." It's not even launched yet, so we're basically playing startup dress-up. But here's the real kicker: they didn't want me for web development. They want me to handle marketing and business development. Me. The guy who can barely market himself on social media without experiencing physical pain from…  ( 4 min )

Why Simplicity Matters More Than Complexity The principle “Less code — more meaning” is a cornerstone of development philosophy. It can be summed up like this: the less code you write, the clearer, more efficient, and more reliable your program becomes. Simple code is easier to maintain, scale, and optimize — all of which directly affect the long-term success of a project. The amount of code is not a measure of a programmer’s productivity or effectiveness. Writing more code doesn’t mean you’ve done a better job. What matters is creating a solution that meets the task's requirements without unnecessary complexity. Just like in art — where minimalism is often considered elegance — simplicity in code is a sign of mastery. 📌 Example 1: Simplifying Conditional Logic if (x > 0) { result = 'positive'; } else if (x 0 ? 'positive' : 'negative'; This single line does the same job, reducing code volume without sacrificing clarity. 📌 Example 2: Using Built-in Browser APIs document.getElementById('my-element').style.display = 'none'; Or, even more idiomatically with classList: document.getElementById('my-element').classList.add('hidden'); And in your CSS: .hidden { display: none; } Using native APIs not only reduces dependencies but also makes your code more transparent, lightweight, and future-proof. 1. Easier Maintenance: 2. Better Performance: 3. Cleanliness and Elegance: The principle “Less code — more meaning” teaches developers to focus on building solutions that are both effective and easy to understand. “Perfection is achieved not when there is nothing more to add, but when there is nothing left to take away.” That’s the essence of clean code — solving as much as possible with as little as necessary.  ( 4 min )

This post is my submission for DEV Education Track: Build Apps with Google AI Studio. So I decided to play around with the Google AI studio and in the process I built a Card Matching Game with an AI opponent. The game logic involves a human player and an AI taking turns to flip two face-down cards to find matching pairs. I prompted Gemini to define behavior like card flipping, score tracking, and memory-based AI decision-making. I also added a fun feature where the card image theme changes after each game from animals to emojis to space objects. Key prompts I used: “Build a card matching game where the player competes against an AI opponent. Cards are displayed face-down in a grid with a black back design.

OpenWebStart (OWS) is an open-source implementation of Java Web Start (JWS), a technology that allowed launching Java applications directly from a web browser. While OWS aims to provide a modern and maintained solution for JWS applications, it faces several security considerations, particularly in the context of modern browser security models. Here's a breakdown of security issues with OpenWebStart and modern browsers: 1. The Fundamental Shift in Browser Security: Modern web browsers have fundamentally shifted away from technologies like Java applets and JWS due to inherent security risks. Browsers are designed to be "sandboxed," meaning they isolate web content from the user's local system. JWS, by its nature, allows applications to run outside this strict browser sandbox, directly on the…  ( 6 min )

Building search that actually understands what users mean beyond simple keyword matching is one of the toughest challenges for dev teams today. Semantic search, which “gets” intent and context, usually requires complex infrastructure, expensive GPUs, and tons of maintenance. That’s why I built Vecstore, an AI-powered search API that adds context-aware image and text search, plus detailed content moderation, to your app in minutes without the hassle of managing GPU servers or complex pipelines. Why traditional search falls short Most apps rely on keyword matching or basic filters. But users don’t think in keywords; they think in concepts and meaning. For example: Searching “movie about billionaire in a flying suit” should return Iron Man Finding images of “girl holding a guitar” shouldn’t require exact tags or filenames Getting this right usually means setting up expensive GPU instances, managing ML models, and dealing with infrastructure that quickly becomes a headache. How it works import requests url = "https://api.vecstore.app/search" headers = {"Authorization": "your_api_key"} data = {"text": "mountain sunset"} response = requests.post(url, headers=headers, data=data) print(response.json()) Who it’s for SaaS products wanting smarter search without building from scratch E-commerce platforms needing fast, relevant product discovery Internal tools that rely on intuitive content search Enterprises looking to add AI-powered moderation and search at scale NSFW Detection with Detailed Labels Beyond search, Vecstore includes powerful content moderation through AI-powered NSFW detection. It doesn’t just flag content as safe or unsafe — it provides detailed labels like “weapons,” “explicit,” or “hate symbols” along with confidence scores. This helps you understand exactly what kind of content you’re dealing with and take appropriate action automatically. If you’re curious, check out vecstore.app and let me know what you think.  ( 3 min )

What is a String? Java string is a sequence of characters that exists as an object of the class java.lang. Java strings are created and manipulated through the string class. Once created, a string is immutable -- its value cannot be changed. A string is sequence of characters. A class is a user-defined template for creating an object. A string class is a user-defined template for creating and manipulating string objects, which are sequences of characters. String name = "Ranjith"; *"Ranjit" is a string. * It is made of characters: R, a, n, j, i, t.

We’ve handled EHR integrations—Epic, Cerner, you name it—more times than we can count. Every single time, we see teams plan to spend $30–40k, then end up shelling out twice as much. It’s not about bad developers. It’s the hidden costs: extra validation cycles, annual support hikes, and contract “gotchas.” Where Most Startups Blow Their Budget (and How to Avoid It) Validation cycles drain cash. Epic and Cerner both charge $10k–$20k per round of validation—and there’s never just one. We always budget for at least two cycles. Support costs always go up. That $15k/year support contract? Expect it to climb by at least 10% each year. It adds up fast. Custom builds rarely pay off. Unless you have a massive budget and endless time, middleware like Redox wins. For a flat $45k/year, you get one API for multiple EHRs—no more vendor headaches. Real Budget Snapshot for 2025 Integration Upfront Yearly Support Hidden Costs Epic $15–20k $15–35k Two+ validation cycles, support escalation Cerner $10–18k $12–30k Extra validation, sandbox fees Redox (middleware) $0–5k $45k All validation included Our typical client?

If you’re keen on saving time and money on file translation, you’ve probably opted for translation software that retains the formatting of your files.That’s a great start! However, when you’re using translation software with automatic file formatting, it’s essential to learn how to build source files correctly so that you can get the best formatting possible when you download a file translation. In an ideal world, the images, paragraphs, spacing and font properties will all stay the same–with the only change being the language. But have you ever heard of the phrase “garbage in, garbage out?” The reality is that if you have built your file in a way that can’t be read properly by computer software, the output file formatting won’t be optimal.

*6 useful things about AI Chatbots you may not know * 1) They respond better to precise instructions about style and length Many people start with short or general questions and receive broad answers. When you include details such as the tone, word count, or format, chatbots often produce clearer replies. For example, asking to summarise a text in no more than 100 words usually results in a more focused response. This way, you are more likely to get accurate and clear replies. 2) They don’t think in words the way people do Chatbots break text into small pieces called tokens rather than processing whole words. This means even small changes in your prompt, like adding punctuation or rephrasing a sentence, can lead to very different answers. For example, “Explain AI simply” may produce a s…  ( 5 min )

Product development is rarely a straightforward process. It involves ongoing testing, validation, and iteration to ensure the final product truly meets user expectations. When a new product idea gets the green light, it’s not just about asking, “Can we build this?” Product teams must also consider, “How will users interact with it?” and, most importantly, “Will they find it valuable?” Addressing these questions early can prevent costly missteps later and ensure you're solving meaningful problems for the right users.

You don’t need to rebuild your app to add AI agent functionality. Here’s how to plug AI agents into your existing React frontend — and make it actually useful. AI agents aren’t just chatbots or support helpers. They’re autonomous systems that can: Handle lead qualification Automate onboarding and internal flows Generate insights from raw data Trigger actions via API calls or tools like Make.com You can integrate these directly into your React UI — without overengineering or refactoring your entire codebase. Here are practical places to plug in agents: Contact/lead forms → pre-qualify inputs and send structured data to your CRM Dashboards → generate summaries or decisions from data Support sections → handle user questions before human handoff User onboarding → guide users dynamically using real-time logic Let’s say you want to ask an AI agent a question from your frontend. 1. Backend endpoint in Node.js 2. React component to connect to the agent Reply: {reply} You can expand this with state management, loading indicators, or a full chat history. Want to go further? At Scalevise, we’ve built agents that: Talk over the phone (Vapi + Twilio) Automate backend ops (via Make.com) Sync with Airtable, CRMs, email, calendars, and more These agents can live independently or behind a React interface. The frontend becomes a UI shell; the logic lives in your AI backend. Use our free AI Opportunity Scan You’ll get: A personalized report Stack recommendations based on your current tech Use case ideas with real ROI React isn’t going anywhere. But your frontend can do more than just display forms and dashboards.

Some of us joined platforms like LinkedIn just to show who we are. We didn’t spam. We didn’t scam. We didn’t cheat. We simply signed up, filled in real information, and tried to connect. And still, we got banned. Let’s be honest. LinkedIn claims to be a professional platform for all. But its systems treat newcomers — especially students, early-career devs, or people from underrepresented regions — as if they’re a threat. Accounts get flagged. Profiles get banned. Support stays silent. And users are blamed for the very actions they’re prevented from controlling. You get locked out. Then you're told you have too many accounts.

I still remember the first time I ran a visual regression test on a live product. It was right after a late-night deployment- one of those “just a small styling fix” kind of pushes. I hit “run” and waited. When the results came in, the screen lit up with dozens of red highlights. The panic was real. Turns out, our test suite was flagging every little pixel shift and color nuance like the apocalypse was coming. The worst part? Most of it wasn’t even relevant. That was my crash course in what not to do with visual regression testing. If you’re in QA, dev, or even product design, chances are you’ve come across this tool- or at least heard of it. When it works well, it’s a lifesaver. When it doesn’t? It creates noise, wastes time, and erodes trust in your testing pipeline. Let’s talk about the…  ( 6 min )

In the world of AI-assisted development, one of the most common frustrations is receiving code based on outdated documentation.

JavaScript is full of powerful features that make coding cleaner and more efficient. One such feature is destructuring. Destructuring is a syntax in JavaScript that lets you unpack values from arrays or extract properties from objects into distinct variables — all in a clean, readable way. Let’s start with arrays. const colors = ['red', 'green', 'blue']; const first = colors[0]; const second = colors[1]; console.log(first, second); // red green const colors = ['red', 'green', 'blue']; const [first, second] = colors; console.log(first, second); // red green You can also skip elements: const [ , , third] = colors; console.log(third); // blue Objects are even more common in real apps. Destructuring makes it easy to pull out properties. const user = { name: 'Alice', age: 25 }; const name = user.name; const age = user.age; console.log(name, age); // Alice 25 const user = { name: 'Alice', age: 25 }; const { name, age } = user; console.log(name, age); // Alice 25 Cleaner code Fewer lines More readable Useful in modern JavaScript frameworks and libraries  ( 3 min )

📌 Key Insights from Geoffrey Hinton Geoffrey Hinton, a leading voice in AI and often dubbed the “Godfather of AI,” recently warned that many jobs are already being replaced by artificial intelligence, especially in white-collar sectors. AI is rapidly replacing roles that involve routine cognitive tasks, including: Call center staff Paralegals Junior analysts Help desk support Hinton notes: “One person with AI can do the work of ten. That changes everything.” Jobs involving hands-on work and physical dexterity remain harder to automate: Plumbing Electricians Skilled mechanics Construction workers “These tasks are still tough for machines,” says Hinton. “Tradespeople may be safer than many office workers.” Beyond job loss, Hinton highlights a deeper concern: Even if basic income becomes a reality, people may lose their sense of purpose, leading to widespread unhappiness. “We’re heading into a world where many may not feel useful anymore.” Certain jobs are more resistant to automation: Healthcare: AI can assist, but not replace, frontline care. Creative fields and emotional labor: Roles involving originality, empathy, or physical skill remain uniquely human—for now. As AI reshapes the job market, Hinton's message is clear: The safest jobs are those that require human touch—physical, emotional, or deeply creative.

Background Relational database is the most common data storage scheme, and hence SQL naturally becomes the first choice for data processing. However, as the complexity of enterprise applications advances, data operation and processing implemented in SQL begins to encounter many serious problems at framework level. Specifically, it is difficult to migrate complex SQL (stored procedures); it imposes a heavy burden on the database since all processing and computing of data are executed in database, which has become a bottleneck of the whole application; Sharing a database by multiple applications will easily lead to strong coupling between applications. Therefore, more and more modern applications begin to resort to other technologies to process data. Among these technologies, Python is a g…  ( 11 min )

🔹 Problem: 3307 Find the K-th Character in String Game II Difficulty: #Hard Tags: #BitManipulation, #BinaryTree, #Simulation, #Math You're given a list of binary operations and an integer k. The operations describe a string-building process where: 0 → Duplicate the current string. 1 → Duplicate and rotate all characters (i.e., 'a' → 'b', 'z' → 'a'). Starting from the character 'a', the string grows exponentially. You must return the character at the k-th position (1-indexed) in the final string. Since the string size can grow beyond 2^60, directly building the string is impossible.

At Super Payment we adopt an "integration-first" testing methodology, with unit/e2e style tests being applied more sparingly. If you want to read more on why we prefer integration tests to unit/e2e tests then Kent Dodds has done a much better job than I will on explaining the rationale. To understand how our integration tests work at Super, we need to know a bit more about our architecture: At Super, our services are written in TypeScript and each service encompasses a given domain. Each service has it's own DB, SQS queue and EventBridge Bus (or whichever subset it needs). The main way for our services to talk to each other internally is via EventBridge/SQS messages, where EB receives messages as the output of the producing system, and the consuming system binds the EB messages it's intere…  ( 4 min )

Every option we looked at was complicated: Set up a database Learn a new CMS Manage user accounts Pay monthly fees Train our team on another system We're a cybersecurity startup. We move fast. This felt like way too much work just to publish blog posts. All we wanted was simple: someone writes a post, adds an image, pushes code, and it's live. Then it hit me. Why do blogs need databases? We already have Git. We use it every day. It tracks changes, handles collaboration, and stores everything. What if blog posts were just files? What if publishing was just a commit?

Web Development is an ART that only a Web Developer can Craft. Hey folks, Welcome to the wonderful world of Web Development! Here is my take: AI won’t replace web developers — but it’s definitely becoming our new sidekick. It is taking care of the repetitive work so we can focus on solving bigger challenges and building smarter experiences. But AI isn’t the only game-changer in town. Behind the scenes, the entire web stack is evolving — from how our browsers talk to servers (hello, HTTP/3!) to how graphics and code run in your browser (meet WebGPU and WASI).

I'm so excited. I explored NativePHP when I first heard about it for the desktop but I didn't really have a need for it at the time. I had a few ideas but nothing I was sure I wanted to spend a heap of time building. But when they announced support for iOS I was intrigued, then they quickly followed with Android support. I was in! I would consider myself a hobbyist, Laravel developer. I work for a large enterprise that is crusty and old and has no interest in modern tooling, so I'm stuck with what they dictate, so Laravel is just a thing I do out of interest. Having said that, I've worked in enterprise environments and understand a bunch about good architecture / practices. I forget that sometimes. That not everyone has my experience.

AI Is Just Another Excel: What the Spreadsheet Revolution Teaches Us About the Future of Work “High school-trained secretaries are out; college-trained specialists are in.” 1985 U.S. Labor Market Report In the mid-1980s, a silent but seismic shift transformed the modern office—not with a bang, but with a spreadsheet. Microsoft Excel, launched for Windows in 1987, became the killer app of the business world. But its real impact began earlier, with VisiCalc and Lotus 1-2-3. For the first time, a single person with a PC could instantly recalculate an entire budget, payroll, or forecast that previously required teams of clerks and hours of labor. What followed was nothing short of a revolution. Between 1980 and 2000: 400,000+ accounting clerk and typist jobs disappeared in the U.S. The once…  ( 5 min )

Confusion is the slowest force in software. It creeps in silently, then shows up loudly in rework, regressions, and mental fatigue. The faster you move without clarity, the more ground you'll have to reclaim later. Velocity isn't about starting sooner. It's about seeing sharply. Before picking up a ticket, pause and ask: → "Do I truly see this, or am I just moving to feel progress?" In your next pair session, don't dive straight into the code. Start with 15 minutes of alignment. What are we solving? What's unclear? Where could this break us? The fastest teams aren't the ones who move first. They're the ones who rarely have to retrace their steps. This is part of The Stoic Developer Codex, a field guide for those who build with clarity, rhythm, and care under pressure.  ( 3 min )

Javascript strings are primitive and immutable: All string methods produce a new string without altering the original string String concat() String trim() String trimStart() String trimEnd() String padStart() String padEnd() String repeat() String toUppercase() String toLowercase() String charAT() Concat used to add two are more string. Example: let text1 = "Hello"; let text2 = "World"; let text3 = text1.concat(" ", text2); console.log(text3); Output: Hello world 2.String trim() Trim is used to remove the around space of the string. Example: let text1 = " Hello World! "; console.log(text1.length) let text2 = text1.trim(); console.log(text2); console.log(text2.length) Output: 30 Hello World 12 This method removes whitespace only from the start of the string. Example: let text = " Hello!"; let trimmed = text.trimStart(); console.log(trimmed); // "Hello!" This removes whitespace only from the end of the string. Example: let text = "Hello! "; let trimmed = text.trimEnd(); console.log(trimmed); // "Hello!" It pads the current string with another string (repeated) until it reaches the given length, starting from the beginning. Example: let number = "5"; let padded = number.padStart(4, "0"); console.log(padded); // "0005" This is similar to padStart(), but padding is added at the end. Example: let number = "5"; let padded = number.padEnd(4, "0"); console.log(padded); // "5000" It returns a new string with a specified number of copies of the string. Example: let word = "Hi "; let repeated = word.repeat(3); console.log(repeated); // "Hi Hi Hi " It converts the string to uppercase. Example: let text = "hello"; console.log(text.toUpperCase()); // "HELLO" It converts the string to lowercase. Example: let text = "HELLO"; console.log(text.toLowerCase()); // "hello" It returns the character at a specified index.

The 90–90 Rule is a tongue-in-cheek observation about software development that goes like this: “The first 90% of the code accounts for the first 90% of the development time. The remaining 10% of the code accounts for the other 90% of the development time.” In short: the last mile always takes longer than expected. On the surface, this seems absurd—until you’ve actually written code in a production environment. Then it becomes painfully accurate. This article explores how this rule plays out in modern DevOps pipelines, how it affects developer velocity, and why it’s not just about code—it's about everything surrounding it. The 90–90 Rule is essentially a brutal reinterpretation of the Pareto Principle (80/20 rule) and closely aligned with Hofstadter’s Law, which says: “It always takes lon…  ( 5 min )

The 90–9–1 Rule has long been used to describe the participation dynamics in internet communities. It suggests that within most online ecosystems: 90% of users are consumers. They observe, read, or watch, but don’t interact or contribute. 9% of users are editors. They interact with content, modify it, or engage with those who do. 1% of users are creators. They generate the majority of the original content that fuels the platform. This pattern was observed in early web communities like Wikipedia, online forums, and comment sections — and it's still visible today on platforms like Reddit, Stack Overflow, and GitHub. But what happens when you apply this model to modern DevOps? And more importantly — how does the rise of artificial intelligence, especially generative AI and autonomous agents, …  ( 5 min )

In my last post I talked about re-factoring your content from one form into another (blog to video, video to conference talk, conference talk to podcast, etc.). Which is good as far as that idea goes, but there is so much more you can do. In fact, let’s do a thought exercise: Challenge #1: Put 1 minute on the timer, take your hands off your keyboard / phone (meaning: NO INTERNET!) and then: name 10 (or more) sports teams How many did you get? How many more could you have come up with if you h…  ( 8 min )

Today we dive into String Game II, a fascinating extension of character transformations involving two unique operations. With string doubling and alphabetic increments — plus a huge value of k — this problem becomes a perfect exercise in bit-level simulation and reverse tracking. Let’s unravel the logic, fast-forward through time, and locate that elusive k-th character! 🚀 You're given: A starting string word = "a" A list of operations, where: 0 means append a copy of the current string. 1 means transform each character to its next alphabet and append it. A large integer k Each operation changes the string. Your task is to find the character at position k (1-indexed) after all operations are applied. ✅ Constraints: 1 ≤ k ≤ 10^{14} — too large to build the string explicitly. At most 1…  ( 5 min )

💡 Bulb Toggle Project Using HTML, CSS & JavaScript Hey devs 👋🏽 I recently built a simple Bulb Toggle Project as part of my learning journey. Even though I'm focused on backend development, I challenged myself to create a small frontend-based project using HTML, CSS, and JavaScript — and it turned out to be both fun and educational. The idea is simple: A lightbulb turns on and off when you click a button. This helped me understand: DOM manipulation in JavaScript Basic CSS styling How HTML structure connects with logic HTML (structure) CSS (styling the bulb and page) JavaScript (to handle the toggle logic) There's a bulb image (off state by default). A button controls the bulb. When clicked, JavaScript changes the image to the "on" or "off" version. Here’s a quick view of the logic in JavaScript: js let bulb = document.getElementById("bulb"); let btn = document.getElementById("btn"); btn.addEventListener("click", () => { if (bulb.src.includes("bulb-off")) { bulb.src = "bulb-on.png"; btn.innerText = "Turn Off"; } else { bulb.src = "bulb-off.png"; btn.innerText = "Turn On"; } }); Simple, right? But it taught me a lot about DOM events and conditions. 🎯 What I Learned As a backend newbie, this project helped me: • Get comfortable manipulating the DOM • Build logic without frameworks • Appreciate how frontend and backend work together ## Video https://www.instagram.com/p/DLTG_s_s54v/?igsh=dnlpbnEydTI1aHk1 👨🏽‍💻 About Me I’m a backend development learner from Nigeria 🇳🇬 Learning one bug and project at a time 😅 Currently working with Node.js, Express, and MongoDB. Let’s connect! ✅ Want to Build It Too? This project is perfect for beginners. You only need: • A text editor (like VS Code) • A browser to test it • Some patience and curiosity 😉 Thanks for reading! Feel free to share feedback or ask me how I did certain parts. You can also follow my journey here on DEV or connect via Hashnode: anizoomy.hashnode.dev Happy coding! 💡  ( 4 min )

Disclaimer Este texto foi inicialmente concebido pela IA Generativa em função da transcrição de uma live do Dev Eficiente. Se preferir acompanhar por vídeo, é só dar o play. Introdução Quando desenvolvemos sistemas, frequentemente precisamos decidir até onde devemos nos proteger de influências externas. Devemos sempre criar camadas anticorrupção para isolar nosso domínio? Ou existem situações onde essa proteção adicional não compensa? Neste post, vamos explorar justamente como podemos decidir sobre este tema. Segundo o livro Domain Driven Design, uma camada anticorrupção é um meio de ligar dois contextos delimitados. A ideia central é que você tem dois contextos (ou sistemas) que precisam se comunicar, mas você quer limitar a influência de um sobre o outro. Embora o livr…  ( 5 min )

To refresh my memory for AWS and Terraform implementation basics, I decided to implement the AWS edition of the Cloud Resume Challenge. The GitHub repo for this project, including deployment notes, is here. The README for the repo contains a basic explanation of the architecture, so I won't repeat all that here. The purpose of this post is to discuss what I learned while implementing this project (and it was a lot!) I've been an Infrastructure specialist for nearly my entire career (Networking, SANs, storage, data replication, DR, and some server work) so getting into the nitty-gritty of an application deployment on the cloud was... educational. (And by "educational" I mean a lot of time spent with the Terraform AWS Provider documentation, Google, ChatGPT, and banging my head against my de…  ( 6 min )

AI Is Collapsing the Front‑End / Back‑End Divide (One‑prompt UIs, many‑layer responsibilities) Software is crossing a new threshold: AI can now write most of the UI layer for us. Tools like v0.dev generate React + Tailwind from a single prompt, while Bolt.new scaffolds a full app in minutes. The result? “Front‑end” roles are migrating toward full‑stack ownership. AI already covers layout, components, and even micro‑animations, freeing developers to tackle deeper engineering tasks—data, auth, business logic. Job descriptions are catching up: companies increasingly look for React plus SQL and queue expertise in a single profile. Studies show AI coding assistants lift completed tasks by ~26 %. In‑house agents reclaim hundreds of thousands of engineer‑hours each year by automating boilerplat…  ( 4 min )

In C#, we have a powerful feature that can help us to reference methods for future execution. This implementation is the Delegate type. Specifically it defines methods, parameters and, return type. Think about delegates as Callback method it is passed into other methods.

This post is my submission for DEV Education Track: Build Apps with Google AI Studio. Prompt I used: Build an app that generates personalized tarot cards with unique imagery using Imagen, paired with Gemini to provide interpretations and meanings for each card. https://mystic-glimpse-ai-tarot-reader-657855663298.us-west1.run.app/ My Development Process: Built the core logic using Gemini 1.0 Pro for text generation, then passed image descriptions to Imagen 2. Initially struggled with inconsistent outputs; solved by adding strict output formatting rules. Integrated user feedback loops (e.g., "Generate another card for the same query"). Insights gained: Prompt Engineering: Specificity is critical. E.g., adding "Include symbolic elements like animals, celestial bodies, or archetypal objects" improved image relevance. Ethical Considerations: Added disclaimer about AI-generated spiritual content. Tech Limitations: Imagen occasionally misinterpreted abstract symbols (e.g., "intertwined vines" became chaotic blobs). Latency between Gemini → Imagen calls required optimization. My Deployment Notes A full web deployment would require: Gemini API for text generation Imagen 2 via Vertex AI for images Frontend (e.g., React) to render cards Cost consideration: ~$0.002/image (Imagen) + ~$0.0005/interpretation (Gemini) Google AI Studio is great for prototyping, but deploying that app as a public web app without triggering billing, especially via Cloud Run, is very limited. Cloud Run requires a billing account, even for the free tier. Clearly what I can’t do without billing: deploy to cloud run or cloud functions, use backend access to Imagen/Gemini APIs without exposing keys and deploy server-side generation logic without hitting limits. This project demonstrated how Gemini and Imagen can combine to create emotionally resonant AI experiences, ideal for creative or therapeutic applications!  ( 3 min )

Ever feel like social media just ‘gets’ you? Here’s a wild stat: Over 98% of Instagram’s recommended content (think: Reels, Explore, even ads) is powered by artificial intelligence. Yep, that endless scroll of perfectly timed memes, dreamy vacation spots, and oddly satisfying videos? That’s not a lucky guess. It’s AI in social media, quietly working its magic behind the scenes. Ever had one of those moments where you're feeling a little “meh,” and then suddenly a dog in a birthday hat or a nostalgic throwback song hits your feed and instantly lifts your mood? Or you're thinking of buying sneakers and—boom—there's a post about the comfiest kicks. Coincidence? Not even close. I used to think it was spooky how my feed seemed to read my mind.
